BOPP Primerless Base Film Three Layer Co Extrusion Dual Surface Function Control Grade

A film that has to do two different jobs on its two faces needs two different surfaces. In this primerless BOPP base film the structure is three layer co extrusion: a core that carries the mechanical strength, one skin formulated for bonding activity so EVA adhesive grips directly, and the opposite skin corona treated for handling, winding and any secondary printing or lamination step. Each surface is engineered for its role rather than both being a compromise.

Building the function into the structure also makes it possible to tune the film for a specific line. Skin formulation, skin thickness and treatment level can be adjusted for a particular adhesive, a particular coating temperature or a particular downstream print process, and the core can be set for the stiffness a given gauge needs. Converters get a base film matched to their process rather than a general purpose film that has to be compensated for.

• Pre Coated Thermal Lamination Base — Base film for EVA coated thermal lamination film where one face must bond and the other must handle.
• Converters With Specific Adhesive Systems — Plants using a particular EVA grade or coat weight, where skin formulation can be matched to the adhesive rather than the other way round.
• Film That Is Printed And Coated — Structures where one face is printed and the other is adhesive coated, so each surface has a distinct function.
• Thin Gauge Pre Coated Film — Light weight product where the core has to preserve strength while the skins deliver bonding and handling.
• Heavy Gauge Pre Coated Film — Heavier product for demanding lamination work, where core stiffness and surface function are both important.
• OEM And Private Label Supply — Customers who need film made to their own specification and sold under their own brand.
• Line Trials And New Product Development — Converters developing new pre coated products who need film adjusted as the process is refined.

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: Can the two surfaces be specified separately?

Yes. Skin formulation, skin thickness and treatment level are set on the line, so the bonding face and the handling face can each be adjusted to the adhesive and the downstream process you use.
