Zipper trivia: PPE-13 (there is no universally applicable zipper).

Today we'll learn about the PPE-13 zipper. Many people in the dry food bag and garment bag industry are familiar with it. It boasts excellent low-temperature heat-sealing and flatness properties, effectively addressing shrinkage issues with OPP and aluminum materials. It also has broad applicability, but note: not universally applicable. For example, it's not recommended for high-temperature applications above 80 degrees Celsius, low-temperature applications below -5 degrees Celsius, or food bags with strict airtightness requirements. Many have experienced this firsthand. With so many PPE brands on the market, how do you choose? Consider two key factors: temperature and strength stability, and heat-sealing strength with the inner layer, especially the heat-sealing peel strength with the PP inner layer.

Qingdao Longhetai's PPE13 is made with high-quality modified materials. Its heat-sealing temperature has been tested in-house and by a third-party customer. Under the same conditions, compared to a certain Japanese product, its zipper blade temperature is 8-10 degrees Celsius lower, while other indicators are consistent. The heat-sealing peel strength can be easily compared.
