The heat shrinkable film has high shrinkage and puncture resistance. It is used to protect the product during storage and transportation, and can be used for integrated packaging to improve the complete set of protective cross-linked film. Non-toxic, environmentally friendly, high transparency, high shrinkage, good heat sealing performance, High gloss, strong toughness, tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging, etc. It is mainly used in product packaging to replace traditional PVC or PE heat shrinkable films. Cross-linked film as product packaging can effectively prevent particularly vulnerable or rotten commodities such as vegetables and fruits from being damaged in transit. The cross-linked film can also be used as a light and protective external material to achieve the purpose of dust-proof, oil-proof, moisture-proof, waterproof and anti-theft, and can also avoid damage to the product due to uneven force.
1. Environmentally friendly and non-toxic.
2. Comply with SGS inspection standard.
3. High transparency, good gloss, good flexibility, easy to use, and more stable packaging line.
4. The shrinkage rate is large, and the shrinkage rate can easily reach more than 80%. It is suitable for packagers of various materials and irregular sizes. product, which makes the product more beautiful.
5. Good sealing, high strength, suitable for manual, semi-automatic and high-speed automatic sealing and packaging machines It can make packaging more efficient, save manpower and reduce costs.
6. Good cold resistance, can maintain flexibility at -40 ℃ without brittle cracking, suitable for packaging in cold weather Store and transport in cold environment, can be used for food shrink packaging. 7. Moisture and dustproof. 8. The packaging cost is low, which is better than the carton and other material packaging.

Cross-linked film is an advanced shrink film product. The cross-linked film after electronic cross-linking treatment can achieve a two-way shrinkage rate of 80% (traditional POF shrink film is only about 60%). Its high shrinkage rate is especially suitable for high-speed packaging. Machine use, reduce defective rate and save cost.
The cross-linked film is non-toxic, environmentally friendly, high transparency, high shrinkage rate, good heat sealing performance, high gloss, toughness, tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging. It is mainly used for product packaging, Replace traditional PVC or PE heat shrinkable film. Cross-linked film as product packaging can effectively prevent particularly vulnerable or rotten commodities such as vegetables and fruits from being damaged in transit. The cross-linked film can also be used as a light and protective external material to achieve the purpose of dust-proof, oil-proof, moisture-proof, waterproof and anti-theft, and can also avoid damage to the product due to uneven force.
Both cross-linked film and POF shrink film are environmentally friendly materials. The raw materials are PP and PE, which are non-toxic and tasteless. They can directly contact the surface of food and fruit, and are suitable for various daily necessities and food packaging.
Its safety complies with the US FDA (Food and Drug Administration) and USDA (United States Department of Agriculture) standards, and can be exported to overseas countries without special testing.
We provides 0.015mm / 0.019mm / 0.025mm cross-linked film/bag, POF shrink film/bag:
0.015mm or 0.02mm – suitable for conventional packaging, such as books, food and beverages, medicines, health products, wine, toys, handicrafts, clothing textiles, stationery, daily necessities, cosmetics and other outer packaging, the thickness depends on the degree of protection required
0.025mm – suitable for packaging that requires special protection, such as furniture, etc.
The above thicknesses are applicable to any type of automatic or semi-automatic packaging machines currently on the market.
Please refer to the following figure:
When batch packaging is required to cross-linked film or POF shrink film, a heat shrink sealing and cutting packaging machine can be used.
Heat sealing, cutting and packaging machines are divided into fully automatic and semi-automatic packaging machines:
The automatic sealing and cutting packaging machine uses the folding film as the packaging material. The folding film is opened by the triangular plate. It is equipped with a conveyor belt and photoelectric detection.
Semi-automatic requires a human to put the product on the left work surface and press the cutter to complete the sealing and cutting.
After sealing and cutting, the packaged objects will be sent to the shrinking machine, and the hot air with uniform temperature in the heating furnace chamber will quickly attach the shrinkable film to the surface of the product to complete the packaging process.
If your company is unable to purchase additional packaging equipment, there are also companies in the market that help you with packaging. Welcome to inquire.
