Protective Film Performance And Use Requirements

With the continuous development of society and human progress, people's demand for quality of life is constantly improving, and all kinds of new things are constantly emerging. It is this seemingly mundane life that brings us great convenience. In the traditional packaging, our food industry and medical industry are very much in use.

Protective film performance requirements

1、 Protective film is inert to the surface of the material being protected.

2、When using protective film, the material to be protected will have good adhesion to a certain extent. In the process of material handling and processing, the protective film will not warp or fall off.

3、The protective film will have good weather resistance and stability of holding power to a certain extent. After a few days or a long time, the peeling force does not increase significantly and peels off easily. When it is removed, there is no residue on the surface being protected.

4、Low crystallization point.

Protective film requirements

1、Suitable for adhesion: easy to stick and easy to tear.

2、Stable peel force, small change during operation, i.e. the smaller the rise in peel force, the better.

3、Good weather resistance, in the sun exposure conditions, the use period can reach six months to a year.

4、Long storage period, more than one year in storage, no change in quality.

5、No pollution, no corrosion, the adhesive is inert, no chemical reaction with the surface of the material to be stuck.

6、Excellent mechanical properties, tensile strength, modulus of elasticity, elongation, etc. in line with user requirements.

PE protective film production principle

1、 PE protective film adhesive (glue) has viscoelastic polymer, film, tear film.

2、The main factors affecting the viscosity: wetting, penetration.

PE protective film adhesive (glue) has viscoelastic polymers

Film: the adhesive layer can be in close contact with the surface of the object to be stuck, and as far as possible into the grooves of the surface of the object to be stuck, so that the effective contact area increases.

The main factors affecting the adhesion

Wetting: pressure-sensitive adhesive only good wetting of the surface of the bonded material to achieve close contact, to create the conditions for Physico-chemical bonding molecular movement and diffusion: pressure-sensitive adhesive molecules will move to the surface of the bonded material to be bonded material when the two are combined, the bonding distance is less than 5A, physical and chemical bonding will occur.

Advantages of PE protective film

1、PE protective film is easy to stick and easy to tear.

2、Long storage period: more than one year in storage, no change in quality.

3、Peel force stability: little change over time, i.e. the smaller the increase in peel force, the better.

4、Good weather resistance: under sunlight exposure, the use period can reach six months to one year.

5、No pollution, no corrosion: the adhesive is inert and does not react chemically with the surface of the adhered material.

6、Excellent mechanical properties: to meet the user's requirements for tensile strength, modulus of elasticity, elongation, etc.
