Regarding packaging there are different types of shrink film that are used for different uses. Three of the most common types are the POF, PVC and PE shrink film. Each film has different strengths, weaknesses and specific features. The knowledge of these differences will benefit any businesses or individuals to choose the right film for their specific need. Guozhao specialise in high quality shrink films to meet the specific requirement. To be able to choose the best fit for the packaging products helps
POF vs PVC vs PE Explained
POF stands for polyolefin, this is a shrink film made from blend of polyolefins. This material is known for being very clear and very tough. This POF film shrink tightly around the product with heat. POF is commonly used for packaging food, toys, and any goods requiring a secure and aesthetically pleasing package. It provides good product visibility while also giving it some protection. PVC, on the other hand is called Polyviny chloride. PVC films are also very popular for a number of reason but in this case there are downsides compared to POF. Generally it does not shrink quite as tight as POF and may not be quite as clear, but is less expensive and work fine when the need for absolute perfect seal is not as important. Polyethylene (PE) is also common type of shrink film. PE is generally thicker than the others and commonly used for larger items. PE is quite strong but is less clear than either of the POF or PVC alternatives. They both serve very different functions, and the products that are going to be wrapped will play a large role in decision
How PVC Shrink Film Compare to PE for Durability
PVC and PE films have very different characteristics when it comes to durability. The PVC shrink film can be fairly flexible, meaning they can take some amount of bend without breaking or tearing, although it is certainly not recommended that the films are pushed to their limits. The major limitation of using PVC film is that it does not do very well in conditions of stress or extreme temperature and can easily become very brittle when exposed to such conditions. However, in contrast PE shrink film are tougher. They can withstand many different stresses without having a problem. So in the event that a strong and rough product will need to be shipped across the country in the back of a bumpy, overloaded, cargo trailerPE is the only reasonable choice for the job. Heavier objects that might get banged around more in transportation would not suffer from PE wrap being too brittle. Guozhao offers films for specific need. The differences in durability between these films really do matter
What to Watch Out For
There are a couple of things to take into consideration before choosing which film to buy. First is the item you are packaging. Different films are made from different materials and have different advantages. POF or polyolefin film is quite strong and flexibility makes for a very nice and well-wrapped package, also being good for food. PVC or Polyviny chloride film is useful for things such as toys or other things non-food. PVC does not however compare to POF in flexibility. PE or polyethylene film is fairly common, cheap, and strong but is not quite as transparent as other films. The temperature you will be using the film in is another consideration. POF wraps at lower temperatures and PVC requires higher temperature. PE films vary greatly, but some of them are more resistant to temperature differences and still can wrap fine at a lower temperature than PVC. Look of packaging is another important issue. POF has a high gloss and shine and will look amazing on a shelf of items. PVC and PE however have a different texture, and the latter film may not give such an appealing visual package. Cost of film also varies, POF will more expensive, PVC less, PE cheapest. This price difference reflects their differing properties and how much each is used. Guozhao offer many range of films
What Environmental Impacts of POF vs PVC vs PE Shrink Film
When dealing with packaging, the environment impacts that can result from its usage also need to be considered. POF and PE films cause less harm to the environment than PVC film. This is because POF and PE films are more readily recyclable than PVC. Also, when burned they produce a much less harmful and toxic gas emission than that caused by the burning of PVC film, thereby causing much less damage to water and air resources. PVC on the other hand produces harmful chlorine gas when burnt and also causes water contamination if left as a waste product in landfills as it seeps into the soil and water supplies. Some PE films may be manufactured using some renewable resources which is also more beneficial for the planet. Guozhao is concerned for the environment
