How Are BOPP, OPP, and PP Bags Similar?
BOPP, OPP, and PP bags are all made from polypropylene, which gives them high strength, tear resistance, and excellent moisture and heat resistance. These qualities make them ideal for packaging a wide range of products. Additionally, they can be customized with features like easy-open designs and anti-skid coatings for added functionality. Overall, these bags offer durable, reliable packaging solutions for various industries.
How to Distinguish Between BOPP, OPP, and PP Bags
1. Thickness: The thickness of BOPP and OPP is the same. The common thickness range is 0.025-0.05mm.
2. Glossiness: OPP bags typically have a higher gloss, while BOPP bags, although transparent, have a lower gloss.
3. Rigidity: The rigidity of OPP and BOPP bags is similar, while PP bags are softer.
4. Transparency: OPP bags are usually the most transparent, followed by BOPP heat-seal bags, with PP bags having a transparency similar to BOPP.
5. Feel: When touched, PP bags feel softer and more flexible, while OPP bags are more brittle and rigid.
Fabrication Differences
BOPP bags are created through a biaxial orientation process, where the polypropylene is stretched in both horizontal and vertical directions. This results in bags that are strong, durable, and crystalclear—making them ideal for retail packaging and highquality prints.
OPP bags are oriented in one direction, giving them a slightly less durable but still high tensile strength. These bags are commonly used in the packaging of food, textiles, and other lightweight products.
PP bags are not oriented, which means they are softer, more flexible, and moistureabsorbent. They are widely used in products that need water resistance, such as diapers and sanitary products.
