Frequently Asked Questions
Q1
What is OPP heat seal film and what makes it different from regular plastic film?
OPP (Oriented Polypropylene) heat seal film is a biaxially oriented film with a special heat-sealable coating on one or both sides. Unlike regular plastic film, OPP heat seal film offers superior clarity, higher stiffness, excellent moisture barrier properties, and the ability to be sealed at relatively low temperatures, making it ideal for high-speed packaging lines.
Q2
What is the recommended heat sealing temperature range for this film?
The recommended shrink temperature for this OPP heat seal film is between 100°C and 135°C. The exact sealing temperature may vary depending on the sealing equipment, dwell time, and pressure applied. We recommend conducting sealing trials to determine the optimal parameters for your specific application.
Q3
Can the width and thickness of the film be customized?
Yes, both width (in mm) and thickness (in microns) are fully customizable to meet your specific packaging requirements based on your desired specifications.
Q4
What industries or products is this OPP heat seal film suitable for?
This film is widely used across multiple industries, including food packaging (snacks, baked goods, fresh produce), stationery, toys, cosmetics, and other daily necessities. Its transparency, waterproof performance, moisture resistance, and oil prevention properties make it a versatile choice for both flexible bags and roll-form packaging.
Q5
What is the difference between OPP (density 0.91 g/cm³) and CPP (density 0.96 g/cm³) in this product?
OPP (Oriented Polypropylene) has a lower density of 0.91 g/cm³ and offers higher stiffness, better clarity, and excellent printability, making it suitable for outer packaging layers. CPP (Cast Polypropylene) has a density of 0.96 g/cm³ and provides superior heat sealability, softness, and moisture barrier performance, often used as the inner sealing layer in laminated structures.
Q6
What are the shrinkage properties of this film and why do they matter?
The film has a controlled shrinkage of TD ≤2.5% and MD ≤4.5%. Low and consistent shrinkage is critical for maintaining dimensional stability during the packaging process, especially in high-speed automated lines. It ensures that the final package maintains its shape, appearance, and seal integrity without warping or distortion during heat sealing or storage.
