In the field of packaging and industrial applications, film materials play a pivotal role. They are not only widely used in daily life, but also play a key role in many industrial scenarios. Today, let’s take a closer look at several common films.
The first is OPS film, OPS is oriented polystyrene. It has excellent performance due to its excellent molecular directional arrangement structure. As a highly transparent OPS film, ops high transparant film has an extremely high light transmittance of more than 90%, which can make the products in the package clearly presented without reservation, greatly improving the product display effect. It is widely used in the field of food and daily necessities packaging, such as exquisite candy packaging, exquisite cosmetic sample packaging, etc. As a window film, ops window film can effectively block about 30% of ultraviolet rays and a certain amount of heat by using its dense molecular structure, playing a role in building energy saving and indoor object protection. ops shrink film has unique heat shrinking properties. In a heating environment of 80-120℃, it can quickly and tightly wrap products. In the packaging of food, toys, electronic products, etc., it not only protects and fixes, but also improves the overall aesthetics of the product. For example, this film is often used in the packaging of a whole box of chocolate. ops food packaging film strictly follows food safety standards and has good barrier properties to oxygen and water vapor. It can effectively extend the shelf life of food. Freshly baked bread, cakes, etc. can maintain a fresh taste for several days after being packaged with this film.
CPP film, that is, cast polypropylene film, has good flexibility and moisture resistance through a unique casting process. Its flexibility makes it difficult to break even after being bent more than 1,000 times. It is often used in the packaging of snacks, clothing, etc. In potato chip packaging, it can perfectly adapt to the irregular shape of potato chips, and its moisture resistance effectively prevents potato chips from becoming damp and softening, maintaining a crisp taste; in clothing packaging, it can gently wrap clothing to prevent clothing from being damaged by moisture during transportation and storage.
POF film is a heat shrink film with a shrinkage rate of up to 70% and a shrinkage temperature as low as about 120℃, which greatly improves packaging efficiency. In electronic products and gift packaging, POF film can fit the product shape closely and has good impact resistance. It can withstand an impact force of more than 10 joules, effectively protecting the product from damage during transportation. For example, POF film is often used in retail packaging of electronic products such as mobile phones and tablets.
