At present, the application of protective films is very common, including
metal materials, plastics, automobiles, electronic products, aluminum profiles,
signs, and many other industries that must use protective films to maintain the
surface safety of goods. However, at present, there are various types of
protective films on the market, which invisibly increases the difficulty for
manufacturers to purchase protective films.
But don't worry, today I will tell you what are the common protective films
in the market?
At present, there are four common types of protective films on the market,
namely PET protective film, PE protective film, AR protective film, and OCA
protective film.
1. PET protective film
PET protective film is commonly referred to as PVC film, which has
advantages such as hard material, scratch resistance, less prone to yellowing
and oil leakage, multiple reusability, and the ability to improve the exquisite
level of packaging for maintained products. However, it also has defects such as
easy foaming and falling off. Therefore, PET protective film is widely used in
mobile phones, tablets, and other methods.
2. PE protective film
PE protective film is a type of protective film made from LLDPE, which is
relatively soft and has a certain degree of stretchability. The thickness is
usually between 0.05 MM-0.15 MM, and the viscosity varies from 5G-500G according
to usage requirements.
PE protective film is generally divided into two types: one is with strong
adhesive, and the other is completely without strong adhesive. Among them, PE
protective film with strong adhesive, also known as straight line film, is a
type of PE protective film with many grid patterns on the surface. This type of
PE protective film has good breathability, good adhesion, and is not prone to
bubble formation after application. A protective film without strong adhesive is
also called electrostatic film, which is a protective film mainly used for
electrostatic adsorption adhesion, This type of protective film has poor
viscosity and is particularly suitable for use in electroplating processes,
electronic equipment production, processing, maintenance, and processing. It is
worth mentioning that PE protective film is also one of the main protective film
products promoted by Pincheng Adhesive at present.
3. AR protective film
AR protective film is a type of protective film generated from silicone
rubber, PET, and unique materials. This type of protective film has advantages
such as high transparency, non reflective, soft material, strong resistance to
abrasion and scratching, and can be reused multiple times. It is widely used in
the maintenance of mobile phone screens and is recognized as a good screen
protection film currently on the market. However, its price and cost are
relatively high.
4. OCA protective film
OCA protective film has advantages such as good light transmittance and
strong strength, and its current key application is in iPhone screen protection,
which is also a common type of protective film in mobile phones.
At present, there are still some OPP protective films, PVC protective
films, and PP protective films on the market, but their sales market has also
been suppressed by these types of protective films, and they are basically on
the edge of being replaced or eliminated by the market.
