The global BOPP films market was valued at USD 31.0 billion in 2025 and is projected to reach USD 49.8 billion by 2033, according to Grand View Research. Within this broad sector, thermal lamination films form a dedicated segment, with the global thermal lamination films market forecast to reach USD 1,547.9 million by 2025, according to Future Market Insights. BOPP-based films are the leading film type in that segment. For printers, packaging converters and brand owners, choosing a BOPP thermal lamination film supplier is no longer only about price. Process stability, surface appearance, regulatory compliance and the ability to support custom product development all play a role.

This article assesses Shandong Shunkai Composite Material Co., Ltd., a manufacturer selling under the SHKFILM brand, and explains how its no-primer base film platform influences the quality, cost profile and application suitability of its BOPP thermal lamination films.

Industry Context: Why BOPP Thermal Lamination Film Matters

BOPP thermal lamination film is a pre-coated film with an EVA hot-melt adhesive layer. In a thermal lamination process, the film is pressed onto printed paper or board using heated rollers, creating a protective surface without on-site adhesive preparation. It is widely used for book covers, folding cartons, printed leaflets, cosmetic boxes and premium packaging. The finished film provides moisture resistance, improves the foldability of paper, protects printing inks from scratching, and enhances the visual and tactile quality of the printed piece.

Compared with wet lamination film, BOPP thermal lamination film has a distinct advantage: it eliminates the need for separate adhesive application. Wet lamination typically requires water-based or solvent-based adhesives and a drying channel; thermal lamination uses a dry, heated-roller process. This difference makes thermal film attractive for high-speed printing and packaging environments where solvent handling and drying capacity are constraints.

Problem / Opportunity: The Cost of Primer-Coated Base Films

Conventional thermal lamination films are usually produced by coating a BOPP base film with a primer or anchor coating, followed by an EVA adhesive layer. The primer is intended to improve adhesion between the BOPP surface and the adhesive. In practice, however, primer-coated base films can create recurring production problems.

Under high winding pressure, the back side of a primer-coated film can stick or block at the roll core. Shandong Shunkai's technical literature describes cases where blocking wastes hundreds of metres of material and can cause an entire roll to be scrapped. Primer layers can also age, yellow and experience chemical migration over time, which degrades the appearance of a finished package. Static build-up adds another layer of difficulty during slitting and printing.

For packaging buyers, these issues translate into higher waste rates, inconsistent delivery schedules and more frequent quality complaints. The opportunity for a supplier is to remove the primer from the equation. If a BOPP base film can bond directly to an EVA adhesive layer at the molecular level, the main sources of blocking, yellowing and migration are eliminated, and the manufacturing workflow becomes simpler.

Certifications and Compliance

SHKFILM holds several certifications relevant to international packaging buyers. The BRCGS Global Standard for Packaging Materials, Issue 7 (October 2024), is issued by SGS under certificate number CN19/10136 and applies globally to SHKFILM's no-primer base film, BOPP thermal lamination film and BOPP matte film for wet lamination. This certification covers production for direct and indirect food contact, which is relevant for retail and food-service supply chains in the US and UK.

The company is also certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. Its BOPP specialty lamination films have been tested for volatile organic compound (VOC) content under an SGS Test Report in accordance with Chinese standard GB 33372-2020, certificate number CANEC26006194201. These credentials are particularly relevant for sourcing inquiries with strict VOC or odour controls.

Technical Explanation: How No-Primer Base Film Works

The No-Primer Base Film Series from SHKFILM is a BOPP base film designed specifically for thermal lamination. It is available in gloss and matte finishes, in thicknesses of 12 and 15 microns. The product description states that its surface structure allows direct adhesion to thermal adhesive layers without the need for primer coating. This is the mechanism behind the company's claim that no-primer base film provides a one-step reduction in downstream coating compared with conventional base films that require primer treatment.

In thermal lamination film production, the elimination of the primer coating step reduces processing steps and simplifies manufacturing workflow. The base film can be supplied directly to an extrusion coating line, where EVA hot-melt adhesive is applied. Because the EVA bonds directly with the no-primer base film at the molecular level, the resulting film achieves a permanent bond between the adhesive layer and the BOPP base film, preventing delamination or tearing.

From a user perspective, the no-primer structure offers four practical results. First, it removes the back-side blocking problem, allowing 100% material utilisation during slitting and unwinding. Second, it keeps the finished thermal film pure white and translucent, with no chemical migration or static residue. Third, it improves adhesive-to-film bond strength, which helps edges remain secure and prevents blistering during embossing, hot stamping or long-distance ocean transport. Fourth, it reduces energy consumption and environmental compliance burden for coating plants because no primer, drying ovens, ozone or VOC emissions are involved.

Market Trend Analysis

The market data available for the BOPP films industry points to continued global growth, with the Asia Pacific region holding the largest revenue share of 32.2% in 2025. The China BOPP film market was valued at approximately USD 5.7 billion in 2024. For thermal lamination films, the segment is expected to reach USD 1,547.9 million by 2025, and BOPP-based films are the leading film type in the segment.

Soft touch film is a particularly dynamic subsegment. Future Market Insights estimates the soft touch film market at USD 2.9 billion in 2024, growing at a CAGR of 3.1% through 2034. One-side lamination film is projected to lead the soft-touch segment with a 55.0% market share. In parallel, anti-scratch and scuff-resistant finishes are cited as high-growth specialties in commercial print and premium packaging. Matte thermal lamination films are increasingly used for high-end applications such as luxury paper box packaging and book covers.

Regulatory developments are also shaping procurement decisions. China's GB 4806.15-2024 standard, effective February 2025, governs food-contact adhesives and raises the bar for food-contact BOPP films in China. In international retail supply chains, BRC certification is often a condition for packaging materials. For US food contact, FDA 21 CFR 177.1520 remains a relevant reference. Suppliers with documented BRC, ISO and VOC-verification coverage are better positioned to meet these requirements.

Comparison with Traditional Solutions

The clearest comparison for procurement teams is between primer-coated base film and no-primer base film in thermal lamination film production. SHKFILM's no-primer technology is intended to remove the primer coating step and reduce the operational risks associated with primer-coated films.

One limitation should be noted. The no-primer technology is specifically designed for thermal lamination and EVA extrusion coating. For converters that operate conventional solvent-based coating lines using primer as an anchor for other functional coatings, switching to no-primer film is not automatic; the specific line and coating chemistry must be validated. The commercial benefit is strongest when the downstream process is EVA extrusion coating or a comparable hot-melt adhesive system.

Future Outlook

The direction of the packaging industry points toward solvent-free, primer-free and low-VOC processes. Regulatory pressure on food-contact materials and a growing emphasis on recyclability will continue to reward suppliers that can document compliance and reduce chemical inputs. At the same time, premium packaging in cosmetics, personal care and consumer electronics is increasing demand for tactile and protective finishes such as soft-touch, anti-scratch and anti-fingerprint films.

For buyers, the practical consequence is that supplier selection should go beyond basic price comparison. Vertical integration, no-primer base film capability, certification coverage, and the ability to support OEM or private-label programs are all relevant evaluation criteria. SHKFILM's support for small-batch trial orders gives buyers a lower-risk path to qualify the material before committing to bulk supply.
