0.18mm Flexible PVC Urine Bag Film is Heat Sealable
Translucent Frosted Surface Urine Bag PVC Film
0.18mm flexible PVC urine bag film is heat sealable. The following is a brief introduction:
PVC heat-sealing properties: PVC (polyvinyl chloride) possesses excellent thermoplastic properties. When heated to a certain temperature, its molecular chains begin to move, becoming fluid. Applying pressure at this point allows the PVC film to fuse with other materials or different parts of itself. Upon cooling, a secure seal is formed. PVC is also an excellent choice for radio frequency heat sealing due to its flexibility and polarity, making it ideal for creating seals and waterproofing applications.
0.18mm Thickness Suitability: 0.18mm thickness is ideal for heat sealing. On the one hand, this thickness allows PVC film to absorb heat well during heat sealing, reaching the required temperature and allowing the molecular chains to fully move and seal. On the other hand, it is not too thick, which can increase heat sealing difficulty or result in poor sealing results, such as a weak seal or a hard, brittle seal. Impact of a Translucent Frosted Surface: PVC urine bag film with a translucent frosted surface is typically created during production by adding specific additives or employing specialized processing techniques. This surface treatment generally does not affect the heat-sealing performance of the PVC film, as heat sealing primarily relies on the thermoplastic properties of the PVC material itself, rather than its surface appearance. During the heat-sealing process, as long as parameters such as temperature, pressure, and time are properly controlled, PVC film with a translucent frosted surface can also achieve good heat-sealing results.
Selection of Heat-Sealing Process Parameters: For 0.18mm flexible PVC urine bag film, the heat-sealing temperature can generally be set at around 120°C, the pressure at 0.5 MPa, and the heat-sealing time at 1 second. However, fine-tuning is required in actual production based on factors such as the specific equipment and film material formulation.
