As a professional can-making enterprise integrating production, R&D and sales, Zhangzhou Yucheng Metal Products Co., Ltd. has been deeply engaged in the metal packaging industry since 1996. With decades of food can manufacturing expertise and an unwavering commitment to quality, we have become a trusted supplier of both round and rectangular packaging solutions for the global market.

Our Rectangle Lid, also known as Rectangular Easy Open End or Square Can Lid, is an innovative packaging solution specifically designed for square and rectangular metal food cans. Unlike traditional round lids, the rectangular lid is precision-engineered to match the unique geometry of square food containers, delivering superior space efficiency and distinctive product differentiation. By incorporating a full aperture easy-open mechanism with a pull tab securely riveted onto the lid surface, we transform a standard rectangular end into a user-friendly, tool-free opening solution that enhances consumer convenience while maintaining uncompromised sealing performance.

The Rectangle Lid offers several compelling advantages over conventional packaging solutions. First, it delivers shape-specific convenience: with a simple lift of the pull tab, the lid opens completely along the outer engraved score line, providing full access to the entire can opening—perfect for solid food products like luncheon meat slices, fish fillets, or pet food blocks. Second, it ensures exceptional sealing integrity: our rectangular lids are double-seamed onto can bodies with precision using advanced sealing equipment, creating an airtight barrier that effectively blocks oxygen and moisture to preserve food freshness, flavor, and nutritional value, extending product shelf life from one to five years. Third, we offer full customization flexibility: from dimensions (length × width, e.g., 106.35×60.60mm, 104×75mm, 96×50mm, and fully customizable options), thickness (0.19–0.24mm as required), to internal coatings (clear/gold/white lacquer, meat release lacquer, epoxy phenolic, BPA NI available) and external coatings (lithographed printing, gold lacquer, or clear lacquer).

In terms of structural integrity, our Rectangle Lid is manufactured to exacting performance specifications. The lid features a curl height (typically 1.92±0.20mm to 2.00±0.20mm) and countersink depth (e.g., 3.90±0.20mm) that ensure proper double seaming compatibility. The easy-open mechanism is engineered with precise pop force (15–35N) and tear force (55–90N) to ensure reliable, user-friendly operation without failure. During production, we adopt online high-precision visual inspection equipment to automatically remove products with appearance defects, guaranteeing that every lid meets the highest quality standards.

Our Rectangle Lid is versatile and widely used across various food packaging applications, including: luncheon meat and processed meat products, fish and seafood (tuna, sardines, etc.), canned fruits and vegetables, pet food, and dry food products. In addition to rectangular easy open lids, we also supply complementary round normal lids, round easy open ends, and complete can body solutions to fulfill all your packaging requirements.

At Zhangzhou Yucheng, quality and safety are our highest priorities. We continuously invest in advanced production and testing equipment to ensure every Rectangle Lid fully complies with international food packaging standards, including ISO 9001 certification. Our lids are manufactured using premium food-grade tinplate or TFS (Tin Free Steel), with BPA Non-Intent (BPA NI) formulations available upon request. With decades of industry expertise, robust quality control systems, and responsive after-sales service, we ensure that every customer requirement is met with professionalism and care.
