This is a tough, transparency of bidirectional shrinking heat shrinkable film, shrinkage in the packaging process stable, balanced, soft corners after packaging is complete, toughness, low temperature resistance, not hard, the effective protection of packaged goods. During use will not produce harmful gases, and can meet the requirements of most automatic and semi-automatic packing machine, is an affordable product.

POF shrink film can be divided into ordinary film, high-end film, cross-linked film categories. General film is widely used in food, daily necessities, stationery, metal packaging and other products. High high low temperature shrinkage, contraction force, for applications that require packaging or products of low contractility at low temperature, such as chocolates, CDs, etc. Crosslinked film may accommodate more packaging machinery, particularly suitable for packaging products with special needs, such as lottery tickets, money, electronics, crosslinked membrane better rack effects.

POF market generally optimistic about the future of cross-linked membrane in light of the small packaging replaces PE, PVC film, paper tray. PVC film thickness, crunchy, wet and cold-resistant performance, after sealing the corners hard and sharp, both in production and use of toxic, but POF thin cross-linked film can do, it is difficult to make thick, so some POF weight of product packaging strength was not enough, still cannot replace the PE packaging.

POF shrink film shows its advantages compared with ordinary POF shrinkable film

1. Shrinkage of crosslinked membrane higher than POF film (two way over 70%, ordinary POF film 60%), shrinkage temperature drop.

2. Than POF heat high strength, wide range of heat seal temperature.

3. Crosslinked film packaging membrane surface the friction there is no ordinary POF film prone to delamination problem.

4. Crosslinked membrane aging natural shrinkage and storage reduces weight lower than POF film.

5. Crosslinked film thickness uniformity than non-crosslinked membrane.

6. Crosslinked membrane stiffness and increases the surface hardness, resistance to mechanical scratches on the surface.

7. Crosslinking resistance impact strength higher than that of non-crosslinked membrane.

8. Using a special formula and process control parameters can be made high shrinkage, low shrinkage and contraction force of cross-linked shrink film, and POF film can.

9. Due to initial shrinkage temperature crosslinked membrane reduced, during the packaging process to some extent increase of systolic time intervals, the contraction eased, reducing the deformation and damage by packaging opportunities.

10. Crosslinked film starting with low shrink temperature and wide range of sealing temperature, reducing demands on packaging and shrink equipment, can than use ordinary POF film to some extent reduce the packaging equipment investment.
