Problems solved by technology

[0003] As a common packaging material component, easy-open lids are widely used in milk powder packaging, chicken essence packaging and other food packaging materials. Some foods or beverages have strong acidity or sulfur content, and general easy-open lids will be affected. Corrosion, if stored for a long time, there may even be small cracks or cracks on the surface of the easy-open lid, causing problems in sealing, which will cause the food or drink inside to deteriorate, resulting in quality problems of the product

Embodiment Construction

[0016] 1) Select the aluminum sheet, apply one of the colorless epoxy silicone coatings FTH128 and FH131 on the surface of the sheet forming the outer surface of the easy-open lid, dry it, and apply one of the fluorocarbon coatings Asdon54742 and Duranar on the other side Kinds, drying; colorless epoxy silicone coating coating thickness of 1-2g / m2, fluorocarbon coating coating thickness of 2-3g / m2;

[0017] 2) Cut the sheet, round the edge, shape, form large and small bubbles, score, protect the edge, nail the ring, inject glue, and form the finished easy-to-open lid.

[0018] The selected aluminum sheets are 3104 H18 and H19 aluminum sheets. The outer surface of the easy-open lid is coated with high-temperature-resistant colorless epoxy silicone coating, and the inner surface is fluorocarbon coating. The packaging material containing this product can resist acid and sulfur.

[0019] At 121°C, the product was soaked in 2% citric acid for 30 minutes, and the coating did not fa...

Abstract

The invention discloses a process for manufacturing acid- and sulfur-resistant snap lids, which comprises the following steps of: selecting an aluminum plate, coating a colorless epoxy organic silicon coating on the surface of the plate on which the outer surfaces of the snap lids are formed, drying the coating, coating a fluorocarbon coating on the other surface of the plate, and drying; and sheeting the plate, rounding edges, molding, forming large and small bubbles, nicking, protecting the edges, nailing rings, and injecting glue to form the finished snap lids. The snap lids manufactured by the process are acid and sulfur resistant, and can be used for packaging high-acid and high-sulfur foods or drinks.

Description

[0001] technical field [0002] The invention relates to a manufacturing process of an acid-resistant and sulfur-resistant easy-open lid. Background technique [0003] As a common packaging material component, easy-open lids are widely used in milk powder packaging, chicken essence packaging and other food packaging materials. Some foods or beverages have strong acidity or sulfur content, and general easy-open lids will be affected. Corrosion, if stored for a long time, there may even be small cracks or cracks on the surface of the easy-open lid, which will lead to problems in sealing, which will cause the food or drink inside to deteriorate, resulting in quality problems of the product. Contents of the invention [0004] The object of the present invention is to provide a manufacturing process of an acid-resistant and sulfur-resistant easy-open lid. [0005] The technical scheme that the present invention takes is: [0006] A manufacturing process of an acid-resistant a...
