Four things to know when purchasing warning PVC foldable film. Under some favorable guidance for sellers, different buyers may fall into the trap of purchasing uneconomical products. Therefore, today the editor of Unified Packaging has prepared a four point method for everyone to prevent the occurrence of misunderstandings. It is easy to be led into a misconception when purchasing PET film, which can easily lead to companies cutting corners due to their own imagination. Therefore, when purchasing warning PET film, enterprises should pay attention to the following aspects.

1. Smelling the odor, if the odor is strong has a sour taste, the retention of this PET film is poor, especially in low temperature environments, it will basically crack when stuck to the cardboard box. The stronger the odor, the initial adhesion of the hand is still very sticky, but the adhesive surface will quickly dry lose its adhesion. At this point, cracks appeared on the surface of the PET film. Because the glue is applied unevenly.

2. The brightness of watching movies. Usually, the color of low-quality PET film is dark. This type of PET film has a high probability of breakage poor strength.

3. The thickness of the felt film is generally as good as the felt hard PET film, the actual number of meters will decrease due to the thickness of the film. The film selected for good PET film is relatively soft has good manual stretchability.

4. Look at the color. Usually, the whiter the appearance of transparent PET film, the less impurities it contains to ensure normal adhesion. The PET film below has a certain transparency of 100 meters, which can be seen the paper tube. For yellow PET film, check if there are irregularly distributed white spots on the surface of the PET film. Impurities marks on glue that cannot be wiped off by hand pressure usually have an odor.
