Frequently Asked Questions (FAQ)
What is TPU film made of?
TPU film is made from thermoplastic polyurethane, a type of elastomer that combines the properties of plastic and rubber. This material is known for its flexibility, durability, and resistance to various environmental factors.
How is TPU film produced?
TPU film is produced through a process called extrusion, where TPU pellets are melted and forced through a flat die to form a thin, continuous sheet. The film can then be treated, coated, or laminated to enhance its properties for specific applications.
Is TPU film eco-friendly?
Yes, TPU film is considered eco-friendly because it is recyclable and does not release harmful chemicals during processing. It also has a longer lifespan compared to some other plastics, reducing the need for frequent replacements.
Can TPU film be used in food packaging?
Yes, TPU film is used in food packaging due to its durability, flexibility, and resistance to oils and greases. It helps protect food items from contamination and extends their shelf life.
How does TPU film compare to PVC film?
TPU film is often preferred over PVC film because it is more flexible, durable, and environmentally friendly. TPU does not contain harmful phthalates, which are often found in PVC, making it a safer option for medical and food-related applications.
