Premium 200# (49.55mm) TFS Round Easy Open End | 0.18mm Baosteel Tin-Free Steel Food Can Lid

Optimise your precision food canning line with our high-quality 200# round TFS (Tin-Free Steel) Easy-Open Ends (EOE). Crafted from 100% premium Baosteel raw materials with a precisely controlled standard thickness of 0.18mm, these small-diameter round metal lids are designed for automated packaging operations. They offer superior mechanical strength, excellent internal pressure resistance, and cost-effective corrosion resistance. With an outer diameter of 49.55 ± 0.10 mm, they fit a wide range of industry-standard containers perfectly, making them the ideal choice for compact food packaging. This product is highly suitable for packaging tomato paste, seasonings, dry goods, agricultural seeds, concentrated sauces, and single-serving canned vegetables, beans, and fruits.

Key Product Features:

• 100% Premium Baosteel TFS Substrate: Manufactured using top-grade Baosteel Tin-Free Steel (TFS). TFS features a unique chromium-based surface that ensures excellent adhesion for polymers and coatings, effectively eliminating the risk of filiform corrosion.

• Ultra-thin, High-performance Specification: Designed with a specialized 0.18mm thickness, this lid significantly reduces container weight and raw material costs without compromising structural rigidity or seaming performance.

• Industrial-grade Epoxy-Phenolic Internal Coating: Features a premium gold exterior finish and a high-purity epoxy-phenolic barrier coating on the interior. This specialized chemical barrier effectively prevents acid corrosion caused by high-concentration tomato paste, salt content, or food preservation liquids.

• High-speed Precision Seaming Geometry: Strict tolerance control (49.55 ± 0.10 mm) ensures smooth stacking and efficient feeding into automatic double-seaming equipment, resulting in a 100% leak-proof sealing system. Technical Specifications

OEM/ODM Customisation & Surface Printing Services

We possess robust manufacturing capabilities to flexibly meet diverse customisation needs:

• Appearance Customisation: Beyond the standard gold finish, we offer multi-colour printing, custom branding text, embossed logos, or printed opening instructions based on your AI/PDF design files.

• Coating Formulation Adjustment: We can adjust the interior protective coating formula (e.g., using organosol or aluminium-pigmented coatings) to suit specific contents—such as high-sulfur or high-acidity products—ensuring optimal corrosion resistance.

FAQ

Q1: Why does this 200# (49.55mm) lid use Baosteel TFS (Tin-Free Steel) instead of standard tinplate?

A: Baosteel is a world-class steel manufacturer renowned for the consistent chemical composition of its products. TFS features a highly stable chromium layer on its surface, offering far superior coating adhesion compared to tinplate. For small-diameter 200# lids that undergo rigorous stamping and forming, TFS ensures the interior protective coating remains free of micro-cracks, thereby providing reliable safety and protection for corrosive contents like ketchup.

Q2: Does the 0.18mm thickness compromise the sealing safety or pressure resistance of the can body?

A: Not at all. Thanks to the excellent hardness and tensile strength of the Baosteel substrate, we have thoroughly optimised the 0.18mm specification to withstand the specific internal pressures generated within small 200# containers. The product not only safely passes the standard 0.1 MPa pressure resistance test but also maintains complete seal integrity during transport and storage.

Q3: Can these 200# can ends, featuring an epoxy-phenolic coating, withstand high-temperature sterilisation (retorting)?

A: Yes, absolutely. Their food-grade epoxy-phenolic internal coating features a highly cross-linked, chemically stable structure designed specifically to endure rigorous industrial steam retorting and high-pressure sterilisation processes (with processing temperatures up to 121°C); the coating remains intact without blistering, yellowing, or peeling during treatment.
