Embodiment Construction

[0015] The present invention will be further described in conjunction with specific embodiments.

[0016] The present invention provides a kind of production method of highly laminating matte aluminized film, comprising the following steps:

[0017] Step 1: Prepare high light-transmitting composite particles: the mass percentages of the various raw materials are 20-60% of silica particles, 39.5-79.5% of polyethylene terephthalate and 0.5% of simethicone emulsifier. Mixing, the sum of the mass percentages of each raw material is 100%; then after being centrifuged in a high-speed centrifuge, it is polymerized; then the polymerized material is extruded and granulated through a twin-screw extruder, and then Cool and dry to obtain high light-transmitting composite particles; preferably, the mass percentage of the above-mentioned raw materials is preferably 40-50% of silicon dioxide particles, 49.5-59.5% of polyethylene terephthalate, and dimethyl silicone oil emulsifier 0.5%.

Abstract

The invention discloses a production method of a highly-laminated matte aluminized film. The method comprises the following steps: step 1, preparing high-transmittance composite particles: fully mixing (by mass percentage) 20-60% of silicon dioxide particles, 39.5-79.5% of polyethylene terephthalate and 0.5% of simethicone emulsifier; and performing centrifugalization in a high speed centrifuge so that polymerization reaction can be carried out; performing extrusion and granulation to the material after polymerization reaction through a double-screw extruder and then cooling and drying; step 2, fully mixing 18-35 parts by weight of high-transmittance composite particles with 54-80 parts by weight of PET (Polyethylene Terephthalate), and carrying out melt extrusion by the double-screw extruder and cooling to obtain a PET base film; step 3, performing corona on the surface of the PET base film obtained in the step 2; step 4, laying a glass fiber grid layer on the surface of the PET base film after corona; and step 5, performing vacuum aluminizing by a vacuum aluminizing machine to form an aluminized layer, so as to obtain the highly-laminated matte aluminized film.

Description

technical field [0001] The invention relates to the technical field of film production, in particular to a production method of a high-adherence matt aluminum-coated film. Background technique [0002] Traditional flexible plastic packaging generally uses aluminum foil with a thickness of 6-20 μm. The aluminum foil has a silvery white luster. Printing transparent ink directly on the aluminum foil can have a unique metallic luster. Aluminum foil has good shading properties, gas barrier properties, moisture barrier properties, good thermal conductivity, and electromagnetic shielding properties. Among them, the most prominent is the barrier performance of aluminum foil. Under the premise of sufficient thickness of aluminum foil, it can completely block gas and moisture. Therefore, aluminum foil is an indispensable material in flexible plastic packaging base film and is widely used in pharmaceutical packaging, food Packaging, especially the flexible packaging of high-end produc...
