Description

A kind of electronic product protective film automatic packaging method

technical field

The invention relates to the field of automatic packaging, in particular to an automatic packaging method for a protective film of electronic products.

Background technique

Protective film is the most popular advanced protective mask for electronic products with display screen, such as mobile phone protective film, IPAD protective film, protective film plays an important role in our mobile phone and IPAD protection, but many people do not know it very well , especially the tempered glass film. The special feature of tempered glass film is the use of tempered glass material, which can play a better anti-scratch effect than ordinary plastics, and has better anti-fingerprint and anti-oil effects.
