Hot perforation film refers to shrinkable hot perforation film produced using polyolefin. The difference between this film and common films is that it has many tiny holes on its surface, which can make the hot perforation film have good permeability and permeability, so today we will take you through this material and introduce the characteristics and applications of hot perforation film in detail.

What are the characteristics of thermally perforated films?

High permeability

Compared to the fully enclosed POF heat shrink film, heat perforated film can be more breathable, which can make the circulation of air moisture movement, and thus achieve the effect of extending the product freshness period. The size and density of these holes can be controlled and customized according to customer requirements.


Heat perforated film has very many advantages, if the packaging is fresh products, it can ensure the moisture gathering inside the packaging. It can greatly reduce hot vegetables and fruits, which can greatly reduce the decay situation environmentally.


Good processing properties

Hot perforation film is easy to process into different forms of packaging products, such as cling film, freezer bags, medical supplies packaging, etc.


Environmentally friendly and healthy

Compared with traditional plastic films, thermo-perforated films use fewer chemicals in the production process, which is less harmful to the environment and human health.


What are the applications of thermo-perforated films?


Food packaging:

hot perforation films are used in a wide range of applications, such as meat, fruit, vegetable, pizza packaging, etc. They can make food more breathable, extend the shelf life of food, and maintain humidity, so good packaging materials that are perfect for.


Medical supplies packaging

hot perforation film can be used to package some medical supplies that need ventilation and sterilization, such as masks, dressings, surgical gowns, etc. It can effectively prevent the growth of bacteria and ensure the effectiveness of use.

Medical Packaging

There are also many supplies in the medical industry that need to be kept ventilated and disinfected, such as masks and surgical gowns, which are perforated but can still be very effective in preventing the growth of bacteria and ensuring good usage results.

Packaging for hygiene products

The use of thermally perforated film can be used for sanitary napkins, tissues and other supplies. Because of its breathability it can reduce moisture and mildew inside the product and can keep the product fresh, etc.


Other industries

hot perforation films can also be used in packaging for industrial products, electronic components and other industries to provide effective breathability and freshness for protecting products.


So how is thermally perforated film manufactured?

1. Extrusion molding: Firstly, thermoplastic resin such as polyethylene (PE) or polypropylene (PP) is added to the extruder, and the thermoplastic resin is added to the extruder and extruded into a certain thickness of the original film through heating and high pressure. Some special additives, such as antioxidants and antistatics, can be added during the extrusion molding to meet different usage requirements.


2. Hot pressing process: The original film is processed by hot pressing process, i.e., the film surface is partially melted to form tiny holes under heating. The size and density of these holes can be controlled by adjusting parameters such as temperature, pressure and speed to achieve different permeability requirements. Meanwhile, the mold design can be used to make the thermally perforated film present different shapes and sizes to suit different packaging needs.


3. Testing and packaging: In the production process of thermally perforated films, quality testing of the products is required, such as testing whether parameters such as temperature resistance, mechanical strength and air permeability meet the requirements. After passing the test, the thermally perforated film is wound into rolls and then packaged through cutting and splicing processes.



I believe the above has introduced the advantages and merits about the heat perforated film, and it is widely used, not only in the food industry, but also in medical and hygiene products, etc. His production process is very simple and can be adjusted with different sizes and numbers of holes. The production process is very simple and can be adjusted to different sizes and numbers of holes. Different needs for transparency can be achieved and it is also very helpful for environmental protection.
