    Aluminum foil gasket sealing conditions?

    1. P: Pressure, that is, the pressure exerted. In the process of sealing, even if the sealing layer is heated and melted, if there is not enough pressure, the sealing layer and the container mouth will not be bonded to form a seal.
    2. H: Heat, the temperature at which it is heated. If the sealing layer is heated at a temperature insufficient to melt the sealing layer, the sealing cannot be completed.
    3. T: Time Indicates the time of sealing. Even if the temperature and the acceptability of these two conditions are met, the sealing and process still need to have enough time to complete.

    What is electromagnetic induction sealing technology?

    Electromagnetic induction sealing technology is an American process engineer Jack Palmer in the 1950s invented a plastic bottle packaging sealing technology, its initial purpose is to contain liquid PE plastic bottles to seal, in order to reduce the leakage of the packaged liquid during transportation. The operation method is to use the electromagnetic induction sealing machine to produce alternating eddy currents on the sealing film of the composite metal film (that is, the electromagnetic induction aluminum foil sealing gasket), so that the sealing film is heated and melted, and the sealing film is fused on the bottle mouth under the action of the cap pressure. Because it is not necessary to directly contact the sealing film when the electromagnetic induction generates eddy currents on the sealing film, the bottle cap can be twisted first during operation, and the sealing film can be operated through the bottle cap. In large-scale industrial production, the sealing efficiency has been greatly improved. Therefore, electromagnetic induction sealing technology has revolutionary significance in the packaging industry.

    Aluminum foil cardboard sealing gasket application?

    Aluminum foil sealing gaskets are widely used in medicine, food, beverage, daily chemicals, lubricants, pesticides, condiments and other industries can use aluminum foil sealing gaskets. According to the different materials of the bottle, the corresponding sealing film can be used to produce various materials of aluminum foil sealing gaskets for sealing bottles of different materials, such as: (plastic bottles) PE bottles, PET bottles, PP bottles, PVC bottles, glass bottles, ceramic bottles, organic bottles and so on.

    Classification of aluminum foil sealing gaskets?

    Aluminum foil sealing gaskets according to the different materials of sealed bottles, can be divided into: PET aluminum foil gaskets, PE aluminum foil gaskets, PP aluminum foil gaskets, glass (universal) aluminum foil gaskets (can be sealed bottles of various materials) and so on.

    According to the different structure of aluminum foil gasket, it can be divided into: one-piece aluminum foil gasket and two-piece aluminum foil gasket. One piece aluminum foil gasket, that is, aluminum foil sealing gasket after the sealing operation, the sealing layer/aluminum foil and the liner are still bonded together in the structure of aluminum foil gasket. Two-piece aluminum foil gasket, that is, aluminum foil sealing gasket after the sealing operation, the sealing layer/aluminum foil and the liner will be separated from the structure of aluminum foil gasket.

    According to the different characteristics of the sealing layer of aluminum foil sealing gasket, it can be divided into: ordinary sealing aluminum foil gasket, high barrier aluminum foil gasket and easy to tear aluminum foil gasket. Ordinary sealing aluminum foil gasket is the aluminum foil gasket used in general food, lubricating oil, daily chemicals, pharmaceuticals, etc. High barrier aluminum foil gaskets add a barrier layer between the sealing layer and aluminum foil, which is used to block and protect volatile solvents, strong acids, strong alkalis or highly corrosive substances, such as: pesticides, chemical detergents, gasoline additives and other products. The sealing layer of easy to tear aluminum foil gasket is coated with (or co-extruded) easy to tear layer, so that the sealing effect is not affected at the same time, reduce the adhesive force between the sealing layer and the bottle mouth, and it is easy to tear the sealing film on the bottle mouth when the user uses the product to open the bottle mouth, without leaving aluminum foil or plastic film on the bottle mouth; Easy to tear sealing aluminum foil gasket for high-grade food, health products, functional drinks, cosmetics and other products packaging.
