Advantages and disadvantages of pov and pof packaging film

You are asking about PVC and POF?

PVC film has a high degree of transparency, good gloss, shrinkage rate and other characteristics

POF surface gloss, good toughness, tear strength, heat shrinkage uniformity and suitable for automatic high-speed packaging and other characteristics, is the traditional PVC heat shrinkable film of the replacement product

Flexible films have polyvinyl chloride (PVC) (Shed film)

(1). Polyvinyl chloride (PVC) shed film: it is in the polyvinyl chloride resin by adding plasticizers, stabilizers, lubricants, functional additives and processing aids, calendered into a film. It is characterized by good light transmission, blocking far infrared rays, strong thermal insulation, soft and easy to shape, good adhesion, good weather resistance. Japan in the facilities of cultivation in about 80% covered with PVC film. Its shortcomings are high density (1.3g/cm3), a certain weight of film covering an area of polyethylene film (PE) to reduce 1 / 3, high cost, hardening and brittleness at low temperatures, high temperatures are easy to soften and relax, aids precipitation membrane surface easy to stick dust, affecting light transmission, residual film can not be burned to deal with, because it will be toxic chlorine gas generation.

Polyolefin (POF) environmental protection heat shrinkable film (bags) is widely used in recent years, three-layer **** extrusion of new plastic packaging materials.

Product features: high transparency, good gloss, flexible and tough, cold barrier, vertical and horizontal heat shrinkage, and in the production of packaging process will not produce toxic gases, belong to the global license to use environmentally friendly heat shrink film.

Product application: suitable for food, beverage, frozen products, medicine, daily necessities, toys, cosmetics, light industry hardware and other small and light products.

Product technical characteristics: plastic film thickness specifications were: 15?, 19?, 25?, 30? four. The longitudinal and transverse heat shrinkage rate is more than 60%.

Application requirements: in 1200 mm (mm) tunnel-type shrinkage machine with thermostatic control and thermostatic blowing under the role of the contraction temperature is 150 degrees - 190 degrees between the speed of the conventional 2-5 meters per minute to complete the contraction of the product packaging.
