The difference between polyolefin and PVC in shrink wrapping

The difference between polyolefin and PVC in shrink wrapping

Shrink wrapping is a process of using a shrink film and a shrink wrapping machine to seal or to hold products during distribution to consumers. The main material often used is the polymers of a plastic material. These polymers come in a variety, and each has a different degree shrinking. In most cases, after wrapping a product with a plastic film, it is passed through a heat tunnel using a conveyor belt. In some cases, it involves applying heat using heat can manually.

Shrink film serves a variety of purpose, and some of the producers use it for protection while others use it for displaying their goods. As a producer, when you wrap and shrink an item before distribution, it will remain clean through thus ideal for food products. Also, shrink wrapping acts as tamper evidence.

Here are the commonly used films in shrink wrapping:

PVC Shrink film

Polyvinyl chloride is one of the oldest plastic materials that are used for the shrink wrapping. This plastic can shrink uniformly over a product and is strong enough to wrap items for distribution. It is also clear; this makes it ideal for displaying products in the market. However, unlike other materials, this type of sealing is not recommended as it releases hydrogen chloride into the air and carbon deposits. You will need proper ventilation when dealing with PVC shrinking film. PVC material is good for packaging boxes, small canisters, DVD packaging, and non-consumable items.

Polyolefin shrink film

This is another common shrink film that works well with many products and shrink wrapping machine. Polyolefin is ideal for products that are edible as well as non-edible as it has fewer odors and does not release too much harmful gas to the surrounding. It is strong and can survive a wide range of temperatures. Polyolefin is good for applications like wrapping sports products, toys, drink packaging, stationery, and other related items.

The common machines for shrink wrapping are:

Heat shrink tunnel– this type of shrink wrapping machine is good for high-speed operations. It is available in different sizes and fit in a product line with a conveyor belt. It is good for industries and households that wrap more products in a day.

L-bar sealer– this machine is ideal for different types of products. It has been designed with different sealing bars and can seal many forms of products including the centerfold shrinking. It is easy and efficient as they require minimal manual labor.

Bench-top sealers –they are mainly meant for low output operations as they can wrap relatively few products in an hour.

Heat guns-this type is ideal for light packaging as you have to do it manually.

Comparison between Reverse Osmosis and Ultrafiltration Process

Comparison between Reverse Osmosis and Ultrafiltration Process

Drinking clean and pure water is good for your health. However, before this water is packed using a water filling machine it has to go through a series of processes for purification. These processes vary depending on the nature of the water you want to get. For instance, for mineral water, ultrafiltration is usually the ideal process, unlike the purified water that has to go through reverse osmosis.

In most cases, raw water contains minerals and harmful substance such as bacteria, chemicals, pesticides, pyrogens, and other contaminants. When removing these substances, water has to go through a purification process that includes the ultraviolet rays, reverse osmosis and ultrafiltration purification. Here is the comparison between the ultrafiltration and reverse osmosis.

Reverse Osmosis

In the Reverse Osmosis or RO, water filtration system requires power to operate and usually removes all the dissolved particles that are available in the water. The RO Water Purification system additionally offers prefiltration when you need to purify the contaminated water, and this purifier expels all the germs and bacteria.  Power, in this case, is also needed to boost pressure for osmosis to happen.

Reverse Osmosis usually requires the availability of a large amount of water; If you input 3 Liters of Water into an RO system, you will probably generate one liter of purified water and two liters of wasted water. However, you can make use of the unused water for wiping the floor, cleaning the house and other home remedies.

Most of the domestic RO systems that are accessible online are not fit for desalination which implies they can’t be used to distill the saline water into purified water. Additionally, unbranded RO water systems don’t hold natural minerals effectively.

There are a considerable number of RO Water systems available on the online, and you can get an ideal RO system that is fit for not just expelling the toxic salts and hard metals but removes the minerals that present in the raw water.

Ultrafiltration

The Ultrafiltration, which is also named UF, is another water purification framework that works without power and totally removes and kills the virus, bacteria and different microorganisms present in the water. Unlike UV Water purification system, the UF purifier expels every one of the germs and dead microscopic organisms from the water after it kills them.

The UF Water purifier doesn’t require power since it only requires pressure unto which tap channeled through pipes haves. However, in this case, contaminants such as dissolved salts and minerals are not removed. This method is ideal for making mineral water, unlike the RO that is ideal for pure water.

How efficient are water filling machines

How efficient are water filling machines

When it comes to production bottle water, water filling machine usually come in handy. These machines are responsible for rinsing, filling and finally capping PET bottles. They usually come in various sizes different features. Depending on your production line you should choose the one that best suits your preferences.

The efficiency of water filling machines varies from one to another. There are some that have been automated and integrated into one process. This is where rinsing, filling, and capping are done in one single process. For instance, there is a water machine that can pack and prepare 2000-3000 bottles per hour. This type of machine is only meant to pack mineral water, purified water, and non-carbonated drinks only. The rinsing chamber consists of 8 valves for rinsing, eight heads for filling and three heads for capping. With this features in place, more than 200 bottles can be achieved making it more efficient and time-saving.

Small bottling plants

For small plants, water bottling machines are designed without the inline system. They are made of compact construction that makes them utilize less space while using the monologue modules. They also have a quick changeover, PLC control and motors that are synchronized for easy maintenance. The operator has to load bottles in an air conveyor where the machine rinse and then fills water before capping them. A small 2000-3000 bottles water filling machine is fully automated and requires less maintenance.

Medium bottling plants

Secondly, there water filling machine that handles 4000-5000 bottles in every hour. These machines are fully automatic and pack 200ml to 1500ml PET bottles. They handle mineral water, purified and non-carbonated. These machines usually have 14 valves for rinsing, 14 heads for filling and five heads for assembling. The rinsing, filling plus the assembling process is integrated and fully synchronized making it ideal for small-medium water bottling companies.

 Large Bottling plants

Then there are water filling machines that handle 6000 to 7000 bottles, 8000 to 10000 bottles, 10000 to 12000 bottles and finally 12000 to 15000 bottles. These large have 32 nozzles for rinsing, 32 heads for rinsing and eight caps for capping. It is ideal for large water bottling plants as it has an effective and reliable workhorse.

Rinsing station

At the rinsing station, the PET bottles enter continuous while they are inverted to allow proper rinsing.

Filling station

At the filling station, the rinsed bottles are filled with high-speed filler. This process is consistent and precise to allow the same amount of water to be packed in each bottle.

Capping station

At the capping station, there is non-stop movement of bottles allowing capping to be done continuously. At this station, there is raping capping system that provides enough torque to tighten each cap effectively.

Advantages Of Capital Intensive Compared To Labour Intensive Production In Reference To Water Filling Machine

Advantages Of Capital Intensive Compared To Labour Intensive Production In Reference To Water Filling Machine

With the world moving away from the olden ways and embracing the use of technology especially in making work more accurate and easier, automation in the packaging process provides benefits to the packaging person/company.

The following are the reasons why we should embrace the use of water filling machine 

Ease in use

All water filling machines come with a guide and an easy to use operator interface. The touchscreen at the interface allows the operator to customize it by entering various times and amounts necessary to complete a cycle. This ease of use will be cumbersome if one is to physically several bottles of water in numerous amounts.

Diversity in use

A water filling machine can be used to package different beverages/products to different bottles. Most of the water filling machines require simple adjustments to change from one bottle type to another or one product to another. This would not be achieved easily with manual filling especially where product viscosity and bottle sizes have great variations.

Speed

Once the market demand reaches a certain high level, the production demand is proportionally affected, and thus, the ability of the water filling machine to adjust to such changes makes it advantageous over the manual filling of water bottles. Except for wear and tear, machines do not get tired, unlike human beings. Hence the use of water filling machine facilitates constant, flexible and faster running of services.

Reliable Fills

The use of water filling machine promotes consistency and reliability in the filling process. The producer/ company will not have to look for other ways of getting to know the volume of the fill or using other criteria. The water filling machine ensures that each cycle is completed in the same manner. Consistency and reliability that would be hard to achieve by hand filling the bottles can easily be achieved with this machine.

Room for change

Most water filling machines are manufactured with future growth potential in mind. There is always room for simple additions to water filling machines such as other fill heads that will allow the equipment to grow with the business. This may pose a challenge, especially with labor-intensive production, as usual; the man is resistant or slow to change.

Cheap cost of production

Acquisition of a water filling machine is a one-off thing that when the machine is bought, it will require a few people to control it thus reducing the cost of production, unlike manual filling whereby the cost of production will increase with the increase in the market demand.

Tips for Freezing Food with a Vacuum Sealer

Tips for Freezing Food with a Vacuum Sealer

If you have a problem with food going bad often, then a vacuum sealer machine is your solution. These are machines that can help you get to preserve all types of food including the perishable foods. Freezing foods with a vacuum cleaner is the best way to extend your food’s shelf life. But how do you it correctly? Here are tips on how to freeze food with a vacuum packing machine like a pro:

Pre-Freeze

One of biggest mistakes that people make is wrong food preservation of food using a vacuum packaging machine. To most people, they just put food from the market directly into the bag and vacuum seal them. That is wrong. It is one of the reasons why some foods such as fruits and vegetable may get squashed when vacuum sealed. Pre-freezing is one of the best ways to get the most out of the vacuumed foods. It helps to get rid of air bubbles that usually squashes food. What you need is first to freeze the food and them vacuum seal it. Pre-frozen foods have a longer shelf life compared to those vacuum sealed directly.

Freezing Cooked and Uncooked food

This is another area that most people fail when it comes to the use of a vacuum sealer. These two foods should be treated differently, and that’s where people get it wrong. For cooked dishes such as soups and sauces can be vacuum sealed and they reheat really well while preparing them some days later. But others such as vegetables may not need to be cooked but can be preserved in their raw form. For the cooked dishes such as ground turkey, you can cook and vacuum seal them when you have time to spare. This tip works well in hotels where the time to numerous orders limited and thus precooking dishes is the only way out.

Portion It Out Properly

The preservation effectiveness of a vacuum sealer depends on two things- the size of the paper and the portion. Make food portions depending on the size of the paper bag. The mistake some people make is thinking that they can put a lot of food in a bag and vacuum it. That will definitely flop. Make sure that you’ve made the right portions to ensure that the food as enough space. Make sure that you have the right portion depending on the kind of papers that you’ve. However, the size of the paper should be determined by the size of your vacuum packing machine.

Always label Packages

Another mistake that people make is failing to label to label the packages after vacuum sealing. This is one of the key things that you need to consider for proper food preservation, especially if you are vacuuming a large number of foods. Make sure that you’ve labelled all the foods to ensure that you don’t forget and mix up everything. Write the name of the food or dish so that even if another person visit your kitchen, then make a meal using with minimal efforts.  If the food is expected to last for months, then you must consider the kind of ink that will not fade away with time.

Buy Special Bags

The choice of the bag is crucial when it comes to vacuum sealing food. One big mistake that people make is buying any bag that they find in the market with researching in products ability to keep air and moisture entirely out. It is recommended that you buy paper bags from the original manufacturer of the machine since they have the quality needed to keep the food safe for long. But there are generic or third-party plastic bags that offers high-quality features as well. But you need to do a little bit more research before spending on generics.

Don’t Reuse Bags

Last but not the least is to avoid reusing plastic paper bags. It is a practice that some people have especially while trying to save on the cost of the paper bags. While this may work for some, it is not recommended since it can lead to food damage. Some of the vacuumed food such as raw meat could have left bacterial which will destroy food.

These are vital tips that you should consider when it comes to freezing food with a vacuum sealer. Just follow them, and you will never have a problem with vacuum sealed food going bad.

Why should you buy a heat sealer?

A heat sealer is a machine used to seal items and other thermoplastic materials using heat. This can be with uniform thermoplastic mono-layers or materials having a few layers, no less than one being thermoplastic. Heat sealing can combine two related materials or can join different materials, one of which has a thermoplastic layer.

Most of the sealing companies usually are dedicated to protecting items safe and food from getting damaged when handling and distributing. For refrigerated items, proper sealing is required to keep the products fresh for customer consumption. By keeping in mind the requirements to meet government regulation for plastic sealing, you should get a heat-packing machine is expected to pack and safeguard both short-lived and durable items proficiently. Here are the advantages of heat sealing:

Preserves Food

The main reason for heat sealing is to protect food products such as cheese, meats,   from getting contaminated through air, moisture, dust and other harmful substance that might damage the product before it reaches to a consumer. At the point when sealed products are at the store, the plastic sealing will keep food fresh from bacteria and allergens, allergens or microorganisms from contamination. Products like meat and poultry should be appropriately sealed to avoid a spread of diseases.

Wide Application

While a heat sealing is commonly used in food packaging, it can also be used for various purposes. Heat sealing acts as a cheap alternative for packaging many products that could otherwise need a lot of capital. Most hardware companies use this form of sealing to package their products from external interference such as moisture, dust among others. Packaging products such as cosmetics, bolts, office equipment utilize this form of sealing to cut down the production cost.

Simple Maintenance

Maintenance required for sealing machine is relatively low compared to other options of packaging. Before acquiring a sealing machine in the market, you should first test of it works well to avoid problems later on.

Cost-effective

Heat sealing is a simple, practical technique for putting away harmful substance and safeguarding freshness of the products. Many industries around the globe use this method as it demonstrates a cheap, reliable, safe framework that ensures sealed products are protected during the distribution as well as improves the shelf life.

Lightweight and Compact

Most of the sealing machines do not require a lot of effort when moving them from place to place compared to other forms of packaging. Some of them are even portable and easy to carry around.

Water Filling and Packing Machine

Water Filling and Packing Machine

A water bottling machine is simply a machine used to fill plastic bottles with mineral or purified water. These machines usually function in three major processes which include:

•  Washing the bottle

  • Filling the bottle with water
  • Sealing or capping the bottle.

They are quite effective and have a lot of advantages to the water bottling plants. The benefits include cost-effectiveness as labor costs can be averted, efficiency, reduced contamination, high speed and boosted productivity.

There are different factors to consider when choosing a water bottling machine and they include; Speed and flexibility, capacity, the volume of the bottles, Power consumption, its dimensions so as to know the required space to fit it and the weight.

To understand more about water bottling machines we will need to look at the various types of bottling machines and how they work.

Semi-automatic washing filling and capping machine

This machine as the name clearly states does three functions washing, filling and capping of the water bottles. However, there is a slight difference compared to the automatic one. Being semi-automatic some of the processes will have to be carried out manually. It requires a person to manually place the bottles in the rinsing machine, and then after they are washed collect them and place them in the filling machine. From here, the automatic filling process takes place. On completion of the process, the person will then be required to cap the bottles manually.

Fully automatic rinsing filling capping machine

This type of water filling machine is fully automated and requires no manual work in the process of rinsing, filling and capping. The machine does all the work from the beginning to the finish. They have a bottle washer, filler, and capper. These types of machines are quite effective for water bottling plants with mass production requirements. They are also advantageous in that they ensure that there is limited water wastage and also perfect hygienic products.

Fully automatic linear washing filling and capping machine Linear means a straight line and therefore linear motion can be described as a movement in a straight line. This is an overview of what a linear washing filling and capping machine do. There is an entry and an exit sort of movable desk where the bottles move in a linear direction and the processes of washing, filling and capping done at different stages till the exit. You should note that this type of water bottling equipment requires no manual washing or capping of the bottles.

Sachet/pouch water packing machine

A sachet packing machine is quite different from its counterparts in that it uses a bag or a sachet. They are mostly used for fruit juice and milk but also to package water. A sachet packing machine fills the bag or sachet with water and then heats seals the bag preventing any water leakage. To ensure no contamination since they use ultraviolet sterilization hence giving you a healthy product. They are preferred in some countries because of their environmental friendliness as less plastic is used. These water filling machines also provide cheap and affordable water products and occupy little space in the water bottling plant compared to regular bottles.
