Aluminum foil for bottle cap is a new type of bottle cap sealing material, which not only has the characteristics of being beautiful and easy to open, but also has the function of preventing counterfeit goods. Therefore, it has been widely used at home and abroad for beverage bottles, wine bottles, cosmetic bottles, medicine bottles, etc.
Aluminum foil bottle is mainly used for the packaging of wine, beverages (with or without steam) and medical and health care products, and can meet special requirements such as high-temperature cooking and sterilization. Aluminum bottle caps are mostly processed in a production line with a high degree of automation, so the requirements for the strength, elongation and dimensional deviation of the aluminum foil are very strict, otherwise cracks or creases will occur during processing.
Generally the alloys are 8011-h14, 3003-h16 and 3105 aluminum sheet. The general thickness is 0.20mm-0.23mm and a width of 449mm-796mm. 8011 aluminum alloy is the main pilfer proof bottle cap material. In addition to having good deep drawing performance and low ear-making rate, it is also required to have a certain strength after baking in the lid-making process.
Bottle sealing foil is used for plastic bottle sealing and glass bottle sealing like glass jar. An aluminum foil sealing gasket is added between the bottle body and the bottle cap to ensure the airtightness of the container bottle and prolong the shelf life of the product. The gasket of this sealing method is composed of adhesive sealing layer, aluminum foil, weak adhesive layer, cardboard elastic body, etc.
Insert the aluminum foil gasket into the bottle cap to expose the aluminum foil, and then apply it to the bottle body to tighten the bottle mouth. Using the principle of electromagnetic induction, the aluminum foil on the bottle mouth will generate high heat instantly, and then fuse to the bottle mouth to achieve the function of sealing.
Heat sealing performance is the most important performance of aluminum bottle sealing foil. Generally speaking, there are several important factors affecting heat sealing, including heat sealing temperature, heat sealing strength and heat sealing layer thickness. The heat-sealing temperature affects the heat-sealing strength, and the heat-sealing film thickness in the heat-sealing layer plays an important role in the heat-sealing effect. Haomei Aluminum has both these two bottle sealing materials. Welcome to leave message below to inquire what you need.
