When packaging your products, it’s important to choose the right material for your product. The right material will provide a tight and secure seal that protects your products during shipping and storage. One type of plastic film that’s often used for packaging is PE shrink film. There are many different types of PE shrink films, so you’ll need to decide which type is best for your products.
Polyethylene (PE) is a kind of thermoplastic resin that’s used in the manufacture of shrink wrap film. PE is a very clear, flexible plastic with good strength and elongation. It’s also durable and can withstand harsh environments. In addition, PE is recyclable, which makes it a great choice for your product packaging.
The main advantage of PE heat shrink film is that it has a higher tensile strength and tear resistance than other kinds of plastic films. It is also moisture-resistant, which helps prevent moisture damage to the products that it covers. PE shrink film is also easy to print on and has good clarity.
Another benefit of PE shrink film is that it can be used in conjunction with other packaging materials. This is particularly important for food packaging, where a Styrofoam tray or paperboard container is often required to achieve a professional look. In addition, PE shrink film has excellent cold and freezer performance and can be used with static electricity elimination treatment.
The disadvantage of PE shrink film is that it is brittle in the cold and when frozen, which can lead to cracking and damage to your products. It’s also not compatible with many printers and can develop dust or other contaminants, which can negatively impact your product’s image on display.
PVC is a common alternative to PE, but it’s not as eco-friendly. It contains carcinogenic chemicals and produces a strong odor when heated. It’s also not as flexible or clear as PE, and it can become brittle after heating, which can cause the product to break during shipping.
POF (polyolefin) is a newer type of heat shrink film that’s made from high-quality raw materials. It has a very low melt point and good shrinkage rates. It’s also very transparent and moisture-resistant. It’s available in a wide range of thicknesses, which means you can find the perfect size for your products.
The cost of PE and POF shrink film
is affected by the price of oil, which is a major source of raw materials for these plastics. The prices of these materials are often volatile. If there’s a shortage of oil from OPEC, it can have a big effect on the prices of both raw materials and finished plastic products. This can increase the price of shrink film, but it’s important to weigh all the factors involved before making a decision.
