Have you ever been troubled in purchasing release film? We will tell you about the way to select release film to solve your troubles. In fact, selecting release film is a very simple thing. Now, you can verify the selection of protective film through the following methods:

1. Smell the taste

If the taste is strong and there is a sour odor, the retention of this protective film is very poor, especially in low temperature environments. Basically, the sealing glue stuck to the cardboard box will crack. The stronger the taste, the initial adhesion will still be very sticky, but soon the adhesive surface will become dry and lose its adhesion. At that time, there will be cracks on the surface of the protective film, which is due to uneven coating.

2. Paper tube

The selection of protective film for thick paper tubes is generally to mislead consumers. The production of protective film started from abroad, so the inner diameter of the protective film tube is uniformly 7.6 centimeters.

3. Check the tightness

The process of rolling protective film from semi-finished products to finished products is carried out by machines in strips. There is a certain amount of tension, and if the tension is high, the protective film will be rolled tightly. The protective film should be rolled neatly according to convention, so there are no gaps in the protective film, and the degree of adhesion between adhesive and air is small. This can extend the shelf life of the protective film and maximize the retention of its adhesion.

4. Look at the brightness of the film

Generally, low-quality protective film will have a dark color, and the probability of this type of protective film breaking is very high, with poor strength.

5. The thickness of the hand feel film

Hard protective films are generally inferior, and due to the thickness of the film, the actual number of meters will decrease. The films used for good protective films are relatively soft and have good elongation when pulled by hand.

6. Look at the color

Generally, the whiter the appearance color of the transparent protective film, the less impurities in the protective film, in order to ensure the normal adhesion of the protective film. Protective films below 100 meters have a certain degree of transparency that can be seen in the paper tube. When choosing a protective film, you can also check if there are irregularly distributed white spots on the surface of the protective film. Impurities or adhesive dry marks that cannot be wiped off by hand are usually odorous.
