PET PET bottle and its sealing

The PET PET bottle is characterized by its beautiful appearance and economical use. It is characterized by the development and promotion of inductive electromagnetic sealing technology. It overcomes the shortcomings of the easy leakage of polyethylene pesticide bottles, and it has incompatibility in water and EC pesticides. Shaken position. PET polyester pesticide bottle is a kind of high-tech product with high-density polyethylene as the base layer. It selects the world's most high-quality synthetic polymer as the inner layer to block the organic solvent, and is reinforced with adhesive in the middle. It is a high-tech product. It can effectively overcome the shortcomings of single-layer HDPE bottles that are easy to infiltrate organic solvents, easily deformed, easily corroded, and single-layer PET bottles are permeable to water, impervious to DMF, and not resistant to high temperatures. It is the most novel pesticide bottle at this stage.

PET polyester bottles are economical, bright and colorful.
The pesticide bottle PET sealing film and the production method thereof are characterized by the following steps:

(1) The above-mentioned colored PET film is further compounded with a polyurethane adhesive having a thickness of 0.65-5.00<filament thickness; the polyurethane adhesive is mainly composed of a polyester polyol and an isocyanate reacted with a cross-linked polymer. Compounds; Polyester polyols derived from the dibasic acid (such as: cis-dicarboxylic acid anhydride, azelaic acid, etc.) and an excess of polyols (such as: trimethylol propane, ethylene glycol) esterification derived;

(2) First select high-temperature thermal-bonded PET film for oxidative color change or printing high-temperature color ink or high-temperature roller coloring;
(3) Then use a PET film with a film thickness of 240°C or higher and 1.2-5<thickness> in combination with the above-mentioned composite PET foil to form a pesticide bottle.
