Double plastic beer bottle

A high barrier plastic bottle made from a small amount of PEN (pure, blended or copolymerized) resin and PET (blend or copolymer) resin via a double co-injection molding machine and blow-molding machine. The invention achieves the standard of the canned beer bottle, and the cost is low. Other fluids with stringent barrier properties may also be canned. Solved the problem that the single-layer PEN bottle is expensive; the single-layer NPET bottle technology is immature and the taste is changed; the single-layer PET/PEN (or NYLON) bottle has insufficient barrier and the taste is changed; the production conditions of the coated bottle are harsh and the barrier layer is vulnerable; the three-layer bottle The equipment investment is huge, the bottle wall is adsorbed seriously, and the taste changes. Technology is mature; equipment, raw materials, process are reliable; qualified samples.
