Problems solved by technology

However, the existing traditional laser anti-counterfeiting cannot be directly applied to the heat-sealing layer material, and the secondary compounding of the two-layer material is required to achieve a realistic metal effect and ensure the heat-sealing performance of the material
Moreover, the rigidity and stiffness of the heat-sealing material layer of the traditional formula are relatively insufficient, so that the cost of the material is relatively high, and the flatness of the material is poor

Abstract

The invention relates to a metal tank packing material and a manufacturing method thereof, which comprises the following steps that: (a) a pattern after the design and the plate making is printed on basic material, the basic material adopts a two-way stretch BOPP or a two-way stretch BOPET; (b) solvent-free adhesive is applied on the basic material, the applied quantity is 1.2 to 1.5 g / m <2>; (c) the basic material is preheated, bonded and compounded; the preheating temperature is 50 to 65 DEG C, a polypropylene mixed film or a polyethylene mixed film is bonded and compounded on the basic material; the compound speed is 90 to 120 m per minute; (d) the laminating and the recovery-furl are performed; (e) the preheating temperature is 40 to 60 DEG C, the delivery-furl tension is 2 to 10 kg, the recovery-furl tension is 15 to 25 kg; (f) the curing is carried out; (g) the cutting and the packing are performed. The method makes the direct printing on the packing material, as a standard film, the packing material is directly packed on the unprinted metal tank for packaging, and has the effect of realistic metal sense.

Description

technical field [0001] The invention relates to a new material field, in particular to a metal can packaging material and a manufacturing method thereof. Background technique [0002] In the United States, the European Union and other regions, metal can intelligent packaging materials have been used to replace metal cans for direct printing and packaging to solve the capital-intensive, technology-intensive, high product substitution, large seasonal changes in the market, and high market concentration caused by single metal can printing. A series of industrial problems, and the material is energy-saving, environmentally friendly, anti-counterfeiting, and easy to recycle. SC Johnson in the United States took the lead in using this product for packaging on spray cans, which has driven the development of this product internationally. At present, the annual production of various metal cans in the world is 410 billion. Among them, there are about 320 billion beverage cans, 75 bi...
