BOPET EVA Thermal Film For Printing Packaging

When Jincheng Factory was manufacturing this BOPET EVA Thermal Film for Printing Packaging, it adopted an integrated pre-coating process. The adhesive layer was already coated upon leaving the factory, eliminating the need for on-site glue mixing and application. It can directly be used with fully automatic and semi-automatic heat laminating equipment, completely resolving the problems of traditional wet laminating glue contamination, slow curing, and blistering and delamination.

Our BOPET EVA Thermal Film for Printing Packaging offers two types of surface textures: transparent glossy and matte frosted. The transparent version has high definition and high transparency, accurately reproducing the original colors of the printing; the pre-coated matte version has a fine and premium texture, is anti-glare and non-reflective, suitable for upgrading the high-end printing texture. The product covers a full range of specifications from 12μm to 150μm with a gradient base film thickness. It also supports customization of multiple EVA coating thicknesses such as 06, 08, 12, 15, 18, and 23, allowing for precise matching of bonding thickness according to paper weight, film size, and usage scenarios. It adopts industry-standard double-sided differentiated corona treatment, with the inner corona surface reaching 52-54 dynes to ensure the adhesion strength of the adhesive layer and prevent delamination; the non-corona surface has a 42-46 dynes membrane surface that is smooth and scratch-resistant, suitable for high-speed continuous film coating production.

Relying on high-quality polyester base material and modified EVA hot-melt formula, the product possesses extremely strong comprehensive physical properties. After lamination, it has stable adhesion, resistance to bending, anti-curving, no edge peeling, no delamination, and no blistering or cracking during long-term storage. The entire production process is dust-free and standardized, without solvent residues, environmentally friendly. It is widely applicable to all industries such as printing and packaging, cosmetics and pharmaceuticals, industrial composites, building materials advertising, and cultural and creative paper products. It is equipped with five standardized packaging schemes, meeting the standards for domestic batch production and cross-border foreign trade export delivery.

FAQ

Q1: What are the core advantages of BOPET EVA Thermal Film for Printing Packaging compared to ordinary laminating paper?

This product is a factory-prestressed integrated finished film, requiring no on-site glue mixing and no organic solvent evaporation. It is environmentally friendly, odorless, and safer during production. The heat-press bonding process is fast and efficient, and the laminated film does not bubble, does not curl, is not prone to cracking, and has better adhesion and product stability than traditional wet lamination processes.

Q2: How to choose the appropriate base film thickness and glue thickness?

For regular posters, business cards, and thin paper printing products, you can choose 12-25μm thin base film + regular glue thickness; for packaging boxes, hard cardboard, and industrial composite sheets, it is recommended to use 30μm or thicker base film + high thickness glue. The bonding is more secure, the anti-deformation ability is stronger, and it can be customized according to the hardness of the material.

Q3: How to choose between glossy transparent and matte pre-coated models?

To enhance the brightness of colors, for high-definition display of pictures, and to improve the bright and vivid texture, choose the transparent glossy model; for high-end gift boxes, luxury albums, commercial display items, and anti-glare scenarios, the matte pre-coated model is preferred. It has a higher quality texture, no reflection, and a softer visual effect.

Q4: Will there be problems such as delamination, edge lifting, or rebound after lamination?

No. The product uses high-adhesion EVA modified hot melt glue, combined with a stable corona base surface, and the glue layer is tightly bonded to the base film. After heat-press bonding, the penetration and adhesion force are strong. After bending resistance and rebound tests, it will not delaminate, lift the edge, or separate layers over a long period of use, and is suitable for long-term storage and transportation with bending conditions.

Q5: Can it be adapted to fully automatic high-speed lamination equipment?

Absolutely. The film tension is uniform, the film surface is flat and flawless, the film runs smoothly without deviation or sticking to the roller, the heat-press temperature range is wide and stable, and it can be adapted to most of the current fully automatic and semi-automatic hot lamination production lines. The production yield is high and the loss is extremely low.

Q6: Which packaging method is recommended for export orders?

For domestic regular production and turnover, you can choose simple packaging or horizontal and vertical pallets; for cross-border shipping, long-distance foreign trade orders, it is recommended to choose suspended pallets or export-specific moisture-proof pallets. They effectively prevent moisture, pressure, and damage to the film surface, ensuring the intact quality of the goods upon arrival in overseas markets.
