BOPP self-adhesive bags are made of stretch polypropylene, a type of plastic material widely used in flexible packaging.

These bags are commonly used in various industries such as clothing, electronics, food, and chemicals. Among different types, OPP self-adhesive bags are the most widely used.

They have a sealing line at the mouth, which can be closed by aligning the lines on both sides and pressing tightly. These bags are reusable and do not require glue. A strip of glue is already present at the mouth of the bag, which is covered with a piece of plastic paper when purchased. To use the bag, remove the plastic paper and seal the bag. Although they are disposable, they can be reused if handled carefully.

There are two types of self-adhesive bags based on their edges. The flat edge is used for bags less than 15cm wide, while the lace edge is used for bags wider than 15cm. The lace edge prevents the bag from exploding. For bags larger than 15cm, vent holes can be added to improve packaging efficiency.

BOPP self-adhesive bags have high tensile strength and are lightweight, non-toxic, tasteless, environmentally friendly, and highly transparent. They are ideal for packaging fresh produce, vegetables, fruits, snacks, food, and other related products. Moreover, OPP self-adhesive bags with anti-fog function are more advantageous in this regard. They keep fresh products fresh and prevent fogging or cracking, even when placed in the refrigerator or freezer.

These poly bags are a great convenience in our daily lives.
