POF shrink film
POF Heat Shrinkable Film is an environmentally friendly shrink film, Multi-layer co-extrusion. It can be in direct contact with food, and it is suitable for automatic packaging equipment such as L-type sealing machine and horizontal packaging machine…etc.
The technology of co-extrusion blown and cross-linked film is developed by electronic equipment of POLYOLEFINLX. The molecular structure of the cross-linking makes the film very tough and strong, and it also have good sealing and shrinkage.
Good transparency, it can be directly seen that the packaged goods are easy to be modified to meet the requirements of different strength and packaging performance.
Strong heat resistance, toughness, ductility and high shrinkage, the product itself is not rigid, brittle, and easy to break, ensuring the long-term storage stability of packed goods.
Widely used in electrical hardware, daily necessities, sporting goods, food and beverage, cosmetics, etc. It is suitable for the outer packing of all kinds of products and has the function of beautiful and generous dust-proof protection. Keep the product clean and bright.

POF shrink film production
Use of POF shrink film
Advantages of using POF shrink packaging
Premium quality shrink wrap, AKA high-clarity, decorative shrink wrap.
Made of 100% recyclable materials.
Excellent clarity and glossy shelf appearance; great for consumer products where appearance is critical (toys, games, candies, books, foods, most retail items).
Ability to shrink quickly and completely (shrinks when heated resulting in a finished good as soon as it comes out of the shrink tunnel).
Durable, versatile, low cost.
Excellent for bundling multiple items together, like tissue boxes for example.
Cross-linked POF is great for high-speed applications, providing added strength without compromising clarity and prevents build-up on sealing components.
Polyolefin is more expensive, but more durable- not as effected by temperature changes.
FDA approved for food contact.
Excellent tensile-strength and propagation-to-tear.
Pre-perforated POF is available and allows for even shrink surface, no air pockets.

CUSTOMERS TESTIMONIALS
This product is an excellent product when need to shrink wrap anything, it did meet expectation and will order
I have used other shrink films in the past that just didn’t perform as I thought they should. This product fulfilled my expectations of what I needed. Quality product at a reasonable cost. Shipping was fast, too.
Polyolefin shrink film is great because there is no odor when sealing or shrinking. But it takes a steady hand to use. Not as easy to manipulate as the PVC film.
This shrink film does everything I need and I use it for almost all of my book sales.
