Jinrong New Materials expands packaging materials lineup with release film and sealing tape

Jinrong New Materials Co., Ltd. is broadening its packaging materials portfolio with Release Film and Permanent Bag Sealing Tape for adhesive converting, flexible packaging, and e-commerce logistics. The move targets manufacturers and distributors that need controlled release surfaces, secure closures, and dependable supply across industrial workflows.

Why it matters: - Release materials are a core input for adhesive converting, label production, flexible packaging, and parcel logistics. - Buyers in these markets need products that match their equipment, storage conditions, and downstream processing requirements. - Jinrong New Materials is positioning two products for those needs: Release Film for controlled separation and Permanent Bag Sealing Tape for permanent closure.

What happened: - Jinrong New Materials Co., Ltd. highlighted its expanded packaging materials portfolio on October 13, 2026. - The portfolio includes Release Film and Permanent Bag Sealing Tape. - The company is based in Jiaxing, Zhejiang, China. - The company lists its address as 168 Rongda Road, Wanghai Street, Haiyan County, Jiaxing City, Zhejiang Province, China. - The company’s website is More information.

The details: - Release paper and release film are used as protective carriers for pressure-sensitive adhesive products. - Release liners help adhesive surfaces separate at the right stage of processing or use. - Depending on construction, a liner may use paper or polymer film and may include a surface treatment that controls release. - The release materials market is tied to pressure-sensitive adhesives, labels, tapes, protective films, and flexible packaging. - For converters and packaging manufacturers, release force, thickness, coating uniformity, and surface properties can affect production behavior. - Jinrong New Materials says Release Film is intended for applications that require a controlled release surface. - Film-based liners may offer dimensional stability, moisture resistance, and surface consistency compared with paper-based alternatives. - Release Film can be relevant to adhesive tapes, labels, protective materials, and composite processing. - Buyers are expected to confirm film width, roll length, thickness, surface characteristics, and release requirements before order placement. - Testing under actual production conditions can help identify compatibility issues before large-scale use. - Permanent Bag Sealing Tape is designed to create a strong, one-time closure on suitable bags and mailers. - Reopening a sealed package typically causes visible damage to the bag or sealing area. - The tape is relevant to courier bags, e-commerce mailers, mailing envelopes, and security packaging. - Compatibility should be checked against the actual bag material, surface condition, adhesive properties, tape construction, storage environment, and application method. - The tape may use different carrier materials, adhesive systems, and release liners depending on the intended application. - Buyers should confirm tape width, roll length, adhesive arrangement, liner construction, and equipment compatibility. - Product testing on polyethylene films, coated papers, laminated structures, and other packaging surfaces can help verify adhesion and seal quality. - The company says customers can request current product specifications, sample availability, packaging details, minimum order quantities, production lead times, and quality documentation. - For export-oriented purchases, customers should also confirm roll dimensions, labeling, carton or pallet arrangements, and transportation conditions. - The company says different production lines may require different widths, thicknesses, roll lengths, or release characteristics. - Related release-material categories include silicone-coated release paper, glassine release paper, double-sided silicone release paper, release paper rolls, and specialized release liners for adhesive products. - Permanent Bag Sealing Tape is designed for mailing bags and e-commerce packaging that require permanent closure.

Between the lines: - The release materials market is being shaped by e-commerce growth, adhesive technology development, and pressure for more efficient converting operations. - Buyers are placing more emphasis on material efficiency, waste reduction, and compatibility with changing packaging formats. - That raises the bar for suppliers on technical data, sample testing, and clear product documentation. - Jinrong New Materials is targeting a market where product fit matters as much as product category.

What's next: - Procurement decisions will likely hinge on sample trials, technical data sheets, and direct confirmation of specifications. - Buyers will need to verify product performance on their own substrates and equipment before scaling orders. - Suppliers that can provide consistent batches, clear communication, and dependable logistics are better positioned to win repeat business. - Jinrong New Materials says customers can contact the company for product catalogs, technical specifications, sample evaluation, packaging details, and order inquiries.
