Reliable BOPET Film China Supplier

Q: What are BOPET films?
A: BOPET (Biaxially Oriented Polyethylene Terephthalate) films are made from stretched polyethylene terephthalate (PET) and are renowned for their high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation.

Q: What are the primary uses of BOPET films?
A: BOPET films are highly versatile and find applications in various industries,, including sustainable energy, healthcare, hygiene, food and beverage, automotive, and consumer electronics.

They are widely used in packaging, particularly for food products to protect against oxidation, solar panels, touch screens, capacitors, identity cards, and coffee foil packaging and pouches for convenience foods.

Q: Are BOPET films recyclable?
A: Yes, BOPET films are 100% recyclable and can be reprocessed into many other products for different applications, aligning with eco-friendly requirements and sustainability goals.

Q: What innovations are available in BOPET films?
A: Innovations in BOPET films include down-gauged conversion substrates, bio & oxo degradable films, universal coated PET films, antimony-free PET films, antistatic PET film for twist wrapping, direct extrusion coatable PET film, special heat-sealable PET films, colored metallised PET film, white PET films, and isotropic PET film.

These advancements cater to various needs across industries, from improving sustainability to enhancing packaging performance.

Q: How do BOPET films benefit packaging and product quality?
A: BOPET films offer numerous benefits, including functional yet eco-friendly features, cost-effectiveness despite their many advantages, attractive aesthetic appeal with excellent gloss and transparency, and versatility in physical characteristics during production to suit specific packaging or product requirements.

Q: What thickness and widths do you usually supply for BOPET film?
A: Typical BOPET thickness ranges from 6 to 80 microns. For flexible packaging, common gauges are 8–25 μm; for labels, insulation and backsheets, thicker films are also available. We can slit rolls up to around 2,000 mm width depending on the grade and your equipment.

Q: When should I choose BOPET instead of BOPP or BOPE film?
A: Choose BOPET when you need higher stiffness, dimensional stability and heat resistance – for example ovenable packs, retort pouches, lidding, or when you want very sharp print and flatness. BOPP or BOPE are often preferred when moisture barrier and low density at lower cost are the main drivers.

Q: What laminate structures commonly use BOPET film?
A: Typical structures include PET/AL/PE or PET/METPET/PE for high-barrier dry foods, coffee and tea; PET/PE or PET/CPP for general food packaging; KPET/PE or heat-sealable PET for lidding and high-temperature applications; and PET-only laminates for labels, cards and graphic media.

Q: Is BOPET film suitable for food contact and can you provide documentation?
A: Yes. Many BOPET grades are designed for food contact when converted properly. We can provide food-contact declarations and related test reports for specific grades and lots on request, including EU and FDA-type documentation where applicable.

Q: How is BOPET film printed and laminated?
A: BOPET films are usually corona-treated or chemically coated to improve ink and adhesive adhesion. They can be printed by gravure, flexo and some digital systems, then laminated with PE, CPP, aluminum foil or other layers using solvent-based, solvent-free or extrusion lamination. Your ink and adhesive supplier can fine-tune the system for each grade.

Q: What are the minimum order quantity and lead time?
A: Typical MOQ for BOPET film starts from around 1 ton per thickness or grade, depending on specification. Lead time depends on thickness, width, coating type and shipping plan, but we can usually arrange trial rolls and sampling quickly to help you test before full orders.

Q: Can you supply special functional PET films such as release, anti-static or high-barrier grades?
A: Yes. Our range includes PET Release Film, Anti Static PET Film, Aluminized PET Film, ALOx PET Film, Photovoltaic Backsheet Film, PETG Shrink Film, PET Heat Transfer Film and other specialty grades for packaging, electronics and industrial uses.

Q: How should I store and handle BOPET film rolls?
A: Store rolls in a clean, dry, cool area away from direct sunlight. Allow rolls to acclimatize to the printing or lamination room before use to minimize tension and curl issues. Follow FIFO and avoid damage to roll edges during handling and loading.

Q: What if I am not sure about the exact BOPET grade I need?
A: You can share your packed product, current structure, machine type and the problems you want to solve (for example, oxygen barrier, high temperature, stiffness, curl, seal strength). Our team will help you select the PET film grade and structure that best fits your line and target market.
