Frequently Asked Questions
QWhat is OPP heat seal film used for?
OPP heat seal film is widely used for packaging food, stationery, toys, and other daily necessities. Its transparent appearance and excellent barrier properties make it ideal for protecting products from moisture, air, and oil contamination.
QCan the width and thickness be customized?
Yes. Both the width (mm) and thickness (micron) of the film are fully customizable to meet your specific packaging requirements. Please contact us with your specifications for a tailored solution.
QWhat is the recommended heat seal temperature range?
The shrink temperature for this OPP heat seal film ranges from 100°C to 135°C, making it compatible with most standard heat sealing equipment used in packaging production lines.
QWhat is the difference between OPP and CPP film in terms of density?
OPP (Oriented Polypropylene) film has a density of 0.91 g/cm³, while CPP (Cast Polypropylene) film has a slightly higher density of 0.96 g/cm³. The choice between them depends on your specific application and sealing requirements.
QHow does OPP packaging help protect products?
OPP packaging provides outstanding waterproof, moisture-resistant, airtight, and oil-resistant properties. This ensures products remain uncontaminated, maintains their quality during storage and transport, and enhances overall product presentation.
QWhat are the shrinkage values for this film?
The film's shrinkage values are TD (Transverse Direction): ≤2.5% and MD (Machine Direction): ≤4.5%. These low shrinkage rates ensure dimensional stability and consistent packaging performance during the heat sealing process.
