Cross Linked POF Shrink Film

KEEPTOP Packaging provide various types of cross linked POF shrink film, such as economic cross linked film, low temperature cross linked film, anti fog cross linked film, etc.

What is cross linked polyolefin shrink film

The cross linked POF shrink film adopts irradiated cross linking technology, the raw material is only PE resin, which makes the polymer chain of the resin change from a linear structure to a network structure.

Compared with standard polyolefin shrink film, cross linked polyolefin shrink film has many performance advantages.

  • Increased Puncture Resistance
  • Higher Shrinkage(up to 80%)
  • Stronger Seal Strength
  • Increased Clarity
  • Stronger heat resistance and cold resistance
  • Less Residue

So the cross linked shrink film is more expensive than the standard shrink film. The higher price is usually justified as it is a premium product over standard shrink film.

detail of cross linked POF shrink film

DES-02B cross linked shrink film has high puncture resistance and superior seal strength.

It is suitable for almost all packaging systems, and is also suitable for packaging goods with sharp edges or irregular shapes.

Regular thickness: micron: 12, 15, 19, 25, 30, 38  (gauge: 50, 60, 75, 100, 120, 150)

DES-02 economical cross linked polyolefin shrink film provides lower cost while ensuring high performance.

The thickness of the film can provide 10 micron (40 gauge).

Compared with the standard shrink film roll, the length of the POF shrink film roll with the same weight is longer.

Longer rolls mean less downtime for roll changes and more time for production.

Regular thickness: micron:10, 13, 17, 22  (gauge: 40, 50, 70, 90)

DES-02FW anti-fog cross linked shrink film is excellent packaging for refrigerated/frozen food.

This anti-fog POF shrink film resists water condensation build-up on the film surface. Provides better clarity to showcase the product.

Regular thickness: micron:11, 15 (gauge: 45, 60)

DES-02DW low-temperature cross linked POF shrink film can achieve high shrinkage at low temperatures.

When heat-sensitive products, aerosols, and other products pass through the heat shrink tunnel, the temperature should not be too high. DES-02DW will come in handy.

Regular thickness: micron:11, 15, 19  (gauge: 45, 60, 75)

More advantages of cross linked POF shrink film

  • As shown in chart 1, the shrinkage rate of cross linked polyolefin shrink film is higher than standard POF shrink film (over 70% in both directions, POF film is 60%), and the shrinkage temperature is lower.
Cross linked shrink film VS Standard POF shrink film
  • As shown in chart 2, compared with Standard POF shrink film, cross linked shrink film has higher heat sealing strength and wider heat sealing temperature range.
  • The lower initial shrinkage temperature and wide heat sealing temperature range of cross linked POF shrink film reduce the requirement and the cost for shrink wrap machines.
  • The cross linked polyolefin shrink film can provide high tensile strength and incredible transparency for high-speed packaging applications.It can also prevent the accumulation of mechanical seal components.Thereby reducing the frequency of replacement of sealing wires and blades.
  • Since the initial shrinkage temperature of Cross Linked Shrink Film is lowered, the shrinkage time is increased to a certain extent during the product packaging process, which eases the shrinkage force and reduces the probability of product deformation and damage.
  • Exceptional strength and puncture resistance.The cross linked POF shrink film of the same gauge is stronger and offers more seal strength than standard polyolefin shrink film.For heavier products, standard shrink film is usually not strong enough.The cross linked film can help ensure products reach customers without being tampered with.
  • Stronger heat resistance and cold resistance. It has good cold resistance and can maintain flexibility at -50°C without embrittlement.
