DKB-10L MULTI-LAYER BLOW MOLDING MACHINE

bottle for edible oil, single-double color lubricants, single-double color cosmetics, 3 layer pesticide,
5 layer food. plastic volume in 0.5-12L.plastic material:PE、PP、PVC、PS、PC、
TPU、ABS、PA、EVA etc.

Features

HMI Touch Screen, Incorporating with PLC system (Optional Siemens/B&R Control) for easy maintenance.
Blowing Unit/ Die Head movement for changing mold easily, as option.
Built with safety devices to provide maximum protection for the machine operator.
High plasticizing capacity extrusion screw is designed to handle material variations.
Plasticizing screw and barrel is precision machined from special nitrogen treated steel.
Water cooling technology controls feed zone temperature.
Chiller circulated hydraulically controlled blow-pin.
When requiring both functions in a single machine, purchase the machine for PVC application and order the additional parts (screw and die head ) for conversion to PE application.

One of three fundamental ways to build CO2 and O2 barrier into PET bottles is to design a multi-layer structure sandwiching PET structural layers around a core layer or layers containing higher-priced barrier materials.

This approach stands to benefit from promising new barrier materials such as nylon-based nanocomposites and “passive-active” barrier systems. The latter are dual-acting formulations of a passive barrier material and an active oxygen scavenger that blocks O2 entry and also absorbs O2 from the head space and contents.

Surface-coating technologies apply a super-thin barrier to one surface of a monolayer PET bottle. Coating equipment is being tailored for specific barrier needs, throughput rates are soaring, and new machine designs are facilitating integration into existing high-speed filling lines.

The “ideal” route to a barrier PET bottle is a monolayer polyester structure. This approach would require blending a barrier resin or O2 scavenger—or both—with PET. Multi-layer or coating equipment would not be needed, and bottle design freedom would remain unfettered. Yet sources concede that few practical “monolayer solutions” are as yet on the horizon, mainly because suitable materials are high-priced.
