BOPET+EVA Roll Film

High-Rigidity BOPET+EVA Thermal Laminating Roll Film Manufacturing & Global B2B Supply

Welcome to Yixing Wangzhe Laminating Film Co., Ltd. (WONLAMI), a premier high-tech enterprise dedicated to the research, development, extrusion composite coating, and international distribution of high-performance functional polymer packaging materials. Founded in 1999, our enterprise brings over 25 years of specialized extrusion lamination experience to serve global commercial print managers, book publishing binderies, industrial packaging convertors, and office stationery distributors across more than 40 countries. As leading BOPET+EVA Roll Film manufacturers, an advanced BOPET+EVA Roll Film factory, and a trusted supplier for BOPET+EVA Roll Film wholesale, we engineer high-stiffness, high-clarity thermal laminating roll films constructed with premium Biaxially Oriented Polyethylene Terephthalate (BOPET) base film co-extruded with high-tack Ethylene Vinyl Acetate (EVA) hot-melt adhesive, delivering superior optical transparency, high tensile modulus, heat resistance, and long-lasting protective encapsulation for photocopies, commercial offset prints, oil prints, menus, and heavy-duty poster displays.

Our manufacturing operations span two modern intelligent production bases strategically located in Yixing, Jiangsu Province, China, and Rayong, Thailand. Covering a total land area of 135 mu with over 90,000 square meters of standardized clean industrial facilities, our dual-base infrastructure operates 10 advanced extrusion coating lines, 29 high-speed automatic slitting machines, 2 multifunctional die-cutting units, and 4 fully automated packaging lines. Supported by a dedicated workforce of over 300 skilled technical professionals, our annual production capacity exceeds 30,000 metric tons. Whether your procurement demands standard 18mic to 350mic thermal laminating rolls, high-gloss or soft matte finishes, maximum master roll widths up to 1800mm, or custom core configurations (25mm, 58mm, 76mm), our production infrastructure delivers micrometer-level gauge uniformity, short lead times, and factory-direct volume value.

BOPET Polymeric Physics vs. BOPP Thermal Co-Extrusion Mechanics

In industrial print finishing and heavy-duty document encapsulation, choosing between Polyethylene Terephthalate (PET) and Polypropylene (PP) substrates depends on required mechanical stiffness, temperature resistance, and dimensional flatness. While Biaxially Oriented Polypropylene (BOPP) thermal roll films offer economical soft feel and high bend elasticity, soft BOPP films lack structural rigidity when encapsulating large-format posters, heavy menus, ID credentials, or display signs that must stand upright without sagging or bowing under environmental heat and humidity.

WONLAMI BOPET+EVA Thermal Laminating Roll Film combines the high mechanical tensile strength and thermal stability of Biaxially Oriented Polyethylene Terephthalate (BOPET) with the low-temperature melting bonding of Ethylene Vinyl Acetate (EVA) resin. BOPET base film exhibits a high Young's modulus (tensile modulus ≥ 4,000 MPa), melting point above 250°C, and exceptional optical clarity with light transmittance exceeding 92%. Co-extruded with an inner low-temperature EVA hot-melt layer (melting point 80°C to 110°C), the film seals tightly onto paper fibers, photocopies, offset inks, and digital oil prints during thermal lamination. The resulting composite laminate delivers rigid lay-flat stiffness, high scratch resistance, superior moisture barrier sealing, and chemical solvent protection.

To support diverse surface mounting, commercial printing, and specialized interactive display needs across global B2B sectors, WONLAMI manufactures a comprehensive portfolio of self-adhesive and roll lamination media. For general commercial book thermal lamination, BOPP+EVA Roll Film provides economical clarity, while Flexible Laminating Roll Film provides 360-degree fold elasticity, and Dry Erase Thermal Laminating Film offers reusable write-and-wipe surfaces:

• High Tensile Stiffness & Dimensional Flatness: Rigid BOPET base substrate prevents post-lamination paper curling, edge bowing, and thermal distortion across large-format sheets.
• Wide Gauge Spectrum (18mic – 350mic): Covers ultra-thin 18mic commercial print finishing up to 350mic heavy board encapsulation for outdoor signs and rigid menus.
• Master Roll Widths up to 1800mm: Precision slitting capabilities fit small desktop laminators as well as wide-format commercial printing presses and industrial packaging lines.
• Multiple Core Specifications (25mm / 58mm / 76mm): Offers 1-inch (25mm), 2.25-inch (58mm), and 3-inch (76mm) heavy-duty paper cores to match all international roll laminator mandrel standards.

Diverse Specialty Product Portfolio & Application Alignment

As an industry-leading polymer composite innovator holding over 20 authorized patents, WONLAMI manufactures a versatile range of thermal laminating, self-adhesive, and functional specialty roll media tailored for distinct commercial printing, educational publishing, packaging, and office stationery workflows:

For commercial printing plants, book binderies, flexible packaging convertors, and office supply brands requiring custom roll widths, roll lengths, corona surface treatment (≥38 dynes/cm), or OEM private-label packaging, our engineering facility produces high-grade custom BOPET+EVA Roll Film products tailored strictly to client machinery and market specifications.

Our manufacturing facilities and products comply strictly with major international quality and environmental management standards, holding official certifications for ISO 9001, ISO 14001, GRS (Global Recycled Standard), BSCI, REACH, RoHS, C-TPAT, and UL. Furthermore, our modern facilities feature rooftop distributed solar photovoltaic power installations to support sustainable, low-carbon manufacturing.

Laminator Machine Calibration & Operation Guidelines

To achieve bubble-free, crystal-clear thermal lamination on commercial roll laminators using BOPET+EVA Roll Film, operators should follow these machine setting recommendations:

• Temperature Setting: Set heated laminating rollers between 90°C and 120°C depending on paper substrate weight, ink density, and laminator speed.
• Nip Roller Pressure: Maintain uniform pneumatic nip roller pressure across the web to squeeze out micro air bubbles and displace paper surface dust.
• Web Tension Calibration: Adjust unwinding mandrel tension moderately to eliminate web wrinkling without over-stretching the BOPET film substrate.
• Post-Lamination Stacking: Allow laminated sheets to cool in flat stacks before passing through automatic die-cutting, foil stamping, or book binding lines.
