Wide mouth glass bottle is generally matched with tinplate cover

In our lives, many of the bottles and cans that are in contact with the tinplate are covered with tinplate, especially some wide-mouthed glass bottles.


Generally, the wide-mouth glass bottle requires high-temperature sterilization when the screw cap is provided, and the sealing property is particularly strong, and has strict requirements on the tinplate material, the coating adhesive and the epoxy.


At present, our domestic tinplate manufacturers basically use imported tinplate, the quality elasticity will be very good, better than the domestic product quality, the price will not be too great. In glass bottled foods, such as fermented bean curd, chili sauce, honey, etc., which do not require high temperature, the inner glue of the bottle cap can be made of low temperature glue, and styrofoam. This type of glue is low because of the low density of the glue material. When the cover is closed, it can be tightened immediately. It has good sealing performance on the bottle mouth, no leakage, and oil leakage. It is very popular among food packaging manufacturers.


Foods such as canned glass bottles, high-temperature bactericidal beverages, caviar, abalone sea cucumbers, etc. must be filled with high-temperature glue when the caps are opened. When the caps are opened, the glue is dense, and the glue is dripped. The surface is very smooth, do not need to be too tight, and enter the high temperature sterilization boiler. When the temperature reaches 110 degrees or above, the epoxy will be closed under high pressure and the bottle mouth to achieve the sealing effect. The cap of this process will be the same as the specification. The low temperature gel cap is slightly more expensive.


There are also some foods that do not require high temperature sterilization, but are highly corrosive. When the food is packaged with tinplate, the adhesive requirements on the surface of the bottle cover are strict and many foods are packaged in the glass bottle cap. If the product fails to be processed, the product will not exceed the shelf life, and the bottle cap will be rusted, which will bring a lot of losses to the food factory.
