BOPP Primerless Base Film Co Extruded Skin Layer For Direct EVA Extrusion No Primer Needed

BOPP is a non polar surface, which is the root cause of the oldest problem in pre coated film production: EVA hot melt adhesive does not naturally grip it. The traditional answer is to corona treat the film and then run a primer coat before the adhesive is extruded, and that primer stage brings its own issues, from drying energy and solvent emission to residue that blooms to the surface later and dulls the finish. This primerless BOPP base film removes the problem at source instead of managing it downstream.

The film is a three layer co extrusion in which one skin layer is formulated for bonding activity, so the surface the EVA meets already has the polarity and chemical affinity the adhesive needs. The other skin is corona treated and behaves as the handling and winding face, or as the print face where a converter wants one. The result is the same finished structure, a BOPP base with an EVA adhesive layer, produced without a primer coater, without a drying oven and without the defects that a primer film can introduce into an otherwise clean process.

• Pre Coated Thermal Lamination Film — The primary use: BOPP base film coated with EVA hot melt adhesive to produce thermal lamination film for the print finishing market.
• Book Cover Lamination — Pre coated film made from this base is used to laminate book covers, jackets and textbook covers where a durable gloss finish is required.
• Commercial Print Finishing — Brochures, catalogues, posters and presentation folders laminated for protection and surface appeal.
• Packaging Box Lamination — Folding cartons, gift boxes and display boxes where a laminated surface improves scuff resistance and print depth.
• Map, Certificate And Document Finishing — Products that need a protective film surface with good clarity and no risk of primer haze.
• Digital And Short Run Print — Small batch laminating shops that want a reliable pre coated film without handling primer chemistry.
• Converters Replacing Foil Or Wet Lamination — Operations moving from solvent based wet lamination to thermal lamination, where a primerless base simplifies the transition.

Q: Are you a manufacturer or trading company?

We are a manufacturer located in Hefei city, Anhui province, China, with our own BOPP and BOPET production lines and an annual capacity of 180,000 tons.

Q: What is your minimum order quantity (MOQ)?

Our typical MOQ is usually 500kg, depending on the exact grade and specification you need.

Q: What is your lead time?

Sample making takes around 3-7 working days. Mass production takes around 10-25 working days after order confirmation.

Q: Do you provide samples? Is there a sample fee?

Yes, we can provide A4 sample sheets for free. For custom samples, a sampling fee may differ based on different specifications.

Q: What shipping terms can you offer?

EXW, FOB, CIF and DDU are available. We also have a dedicated shipping agent to arrange sea, air and express delivery.

Q: What payment methods do you accept?

We usually accept T/T bank transfer with 30% deposit and the balance before shipment. Other payment methods are negotiable.

Q: How does the primerless base film bond to EVA without a primer?

One skin layer is formulated during co extrusion to carry bonding activity, so its surface already has the polarity EVA adhesive needs. The adhesive is extruded directly onto that skin and forms a firm bond without a primer coat.
