Tinplate coating equipment is mainly used for internal and external coating and, at times, can be directly attached behind a printing machine for immediate curing. Main Structure of Coating Equipment Adjustment of coating machine 1. Conveying Section: Refer to the adjustment of the printing machine conveying section. 2. Setting Rubber Roller and Coating Roller (Using […]
Tinplate coatings are broadly classified into internal coatings, external primers (base oil coatings), undercoats (white rubber coatings), and topcoats. Internal Coating: (1) Primary Purpose: Prevents the corrosion of the can wall and contamination of the contents, ensuring prolonged storage. (2) Key Characteristics: Corrosion resistance, excellent adhesion, flexibility, non-toxic, and odorless, meeting food safety standards. Must […]
Aluminum cans, also known as two-piece cans, consist of a can body and a can lid, both manufactured on different production lines using various aluminum alloys. In practice, the can lid is composed of two components: the lid body and the pull-tab, both produced with different alloys and thicknesses of aluminum strips on highly automated […]
Currently, the main types of coatings used for canned goods include epoxy phenolic coatings, epoxy amine coatings, organic solvent coatings, ethylene-based coatings, polyester coatings, acrylic coatings, and epoxy ester coatings. Below is a brief introduction to the characteristics of various resins and the performance and applications of coatings made from them. Epoxy Ester Coatings Epoxy […]

(1) In major tinplate-producing nations worldwide, there is a general trend of no longer establishing new tinplate production units, including those for Tin-Free Steel (TFS). However, developing countries, particularly China, are still in the process of constructing new production lines, experiencing rapid growth. TFS products offer lower production costs and contribute to the conservation of […]
Epoxy Esters Coatings Epoxy ester resin is a product obtained through the esterification process of vegetable oil and epoxy resin. This resin imparts good flexibility and color to coatings. Epoxy ester coatings are primarily used for post-printing varnishing. They are suitable for a wide range of products, including tinplate cans, deep-drawn tins, twist-off caps, crown […]
Epoxy Amine Coatings Epoxy amine coatings are formulated with epoxy resin and amine resin in a certain ratio. They are widely used as protective coatings for the exterior walls of can lids, can bodies, twist-off caps, and sealing caps. The main properties and advantages of epoxy amine coatings are as follows: Clear film appearance […]
With the intensifying competition in the beverage packaging market, reducing the thickness of materials, minimizing wall thickness, reducing costs, improving material utilization, facilitating recycling and convenience of use have become important goals for many can manufacturing companies. One of the key aspects of cost reduction in the production of aluminum cans is reducing the thickness […]
