What is environment-friendly POF shrink film?

A new type of plastic film that shrinks automatically when it reaches a certain temperature.

Heat POF shrink film is widely used in food, flatware medicine, sterilized tableware, stationery and sports goods, craft gifts, printed matter, hardware and plastic products, telephones, electronic appliances and other products.

Packaging, especially in the combined (clustered) packaging of irregular-shaped items or commodities, can prevent moisture and dust, increase the attractiveness of the product appearance, and can also be used to replace all kinds of cartons, which not only saves packaging costs, but also conforms to packaging trends.

What is the use of POF shrink film?

The POF films have a wide range of uses and are fully in line with today’s environmental and non-toxic world consumer trends. This material can not only reduce the user’s packaging production costs, transportation costs, reduce packaging volume, but also greatly increase productivity.
It also has better transparency and can improve product visibility. It can be used in fierce competition and a wide variety of products. Japanese supermarket shelves quickly grab the attention of consumers, and cater to consumers’ psychological characteristics of convenience and economy to bundle and pack goods, which is especially suitable for the packaging and placement of supermarket goods.
Therefore, the same family has developed in Europe and the United States. It has been widely valued and applied.
POF heat shrinkfilm is mainly used in the packaging of various products. If it is environmentally friendly, it will have more effects. For simple examples, such as photo frame factories, milk tea factories, noodle factories, tea cups Factories, pharmaceutical factories, jewelry factories, gift box factories, cleaning companies, etc.

What is the best shrink temperature for POF shrink film?

The thickness and raw materials of the POF shrink film determine the shrinkage temperature and effect. Generally, 1.5 filaments are between 140-150 degrees. The thicker the shrinkage temperature, the higher the shrinkage temperature. It is reasonable to say that the higher the temperature, the better the shrinkage effect. The film will not be damaged, and the speed is directly proportional to the temperature. The faster the speed, the higher the temperature. This should be based on your actual operation to control the temperature and speed to achieve the best results. The POF shrinking process is completed at one time, so it is recommended that the speed be relatively fast, and the temperature should be set relatively higher, so that the effect will be better.

What is the thickness and width for POF shrink film?

Thickness and Width for POF shrink film
Thickness:8.5μ, 10μ,12μ, 15μ,19μ,25μ,30μ, 38μ
Width:from 100 mm to 2500 mm

Technical Data Sheet:

Name Width Thickness Vertical Shrinkage Horizontal Shrinkage
POF Shrink film 100-2400mm 0.012-0.025mm 65% 69%
PE Strecth film 250-1000mm 0.02-0.025mm Tensile rate 1:4
PE Shrink film 150-1000mm 0.02-0.15mm 65% 30%
PVC Shrink film 90-600m 0.02-0.08mm 20-40% 20-50%
PVC Print film 150-450mm 0.03-0.08mm < 3% 48%

Is the production process of POF film harmful to the employees in the factory?

POF production materials are non-toxic, belong to a physical process, do not produce chemical reactions, the production process is non-toxic and tasteless, just a little noise, the workshop temperature is slightly higher, but much lower than the PE production workshop temperature, work intensity It is lower than PE production and has higher requirements for workers.

How to make the heat shrink machine shrink the POF film to achieve the best effect?

Most of the heat shrink machines can shrink. As for the best results, it depends on the working principle and configuration of the machine itself. Of course, sometimes the quality of the film is also a factor. Therefore, it is very important to choose a good shrink wrap machine manufacturer and a POF shrink film manufacturer.

Frequently Asked Questions

What is the cause of wrinkles in POF shrink film?

First of all, if the contraction temperature is not enough, adjust the temperature can be high (the upper part of the wrinkled more, adjust the upper heating temperature, and vice versa, adjust the lower heating temperature); if the temperature is high enough, try to slow down the speed of the conveyor belt, so that the product in the shrink tunnel for a longer time, will improve the shrinkage effect.
Secondly, and the quality of heat shrink film, poor quality POF shrink film affordable impact on the shrinkage effect, if the shrinkage ratio is small, toughness is not enough, change a better shrink film can be.

What should I do if the POF breaks during contraction?

1.Turn the temperature down 5-10 degrees to test, to see if it is caused by too high temperature;

2.Test the uniformity of the thickness of the film, if the thickness difference is large, it should be the film itself is not good quality;

3.If there is a break in the vacant point, if so, to choose a thicker POF film, or cross-linked film to solve the problem.

What happened to the POF film that did not expand when it shrank?

Reason 1: there is not high enough temperature.
Reason 2: too many air holes, shrink off without expansion.
Reason 3: not enough hot air, check the fan.
