Abstract

The present invention relates to a kind of flexible container pack for liquids film, belong to Container Transport packaging film field, it is characterized in that with olefines special elastomer, mLLDPE and LDPE blended, produce flexible container pack for liquids film at little three-layer co-extruded unit.Packaging film tensile strength, puncture resistant, high extensibility and rubbing property, resistance to bending performance significantly improve, the security that liquid bag film is used obviously improves, make in transportation (particularly low temperature, adverse circumstances) that the accidents such as brittle seepage punctures be less likely to occur, virtually reduce cost of transportation, also can not cause environmental pollution because of material loss, transportation safety coefficient increases simultaneously.

Description

Flexible container pack for liquids film

Technical field

The present invention relates to a kind of flexible container pack for liquids film, belong to Container Transport packaging film field.

Background technology

In recent years, container liquid packaging film is used widely as a kind of new model of plastic flexible package, Container Transport packaging film, and common packaging film content has: oily substance, plasticizer, pitch etc. liquid.On market, liquid flexible packaging made from plastic film is mainly polyethylene (PE) co-extrusion film, but firmly sometimes there is seepage at use procedure film bag, cause direct economic loss and some indirect economic loss thereof, so namely, cause loss of material, also can bring pollution to environment simultaneously, bring very large inconvenience to Container Transport liquid material.

Summary of the invention

According to the deficiencies in the prior art, the technical problem to be solved in the present invention is: provide a kind of flexible container pack for liquids film, packaging film tensile strength, puncture resistant, flexibility, resistance to bending performance significantly improve, and liquid bag film is in use safer.

The technical solution adopted for the present invention to solve the technical problems is: provide a kind of flexible container pack for liquids film, it is characterized in that with olefines special elastomer, mLLDPE and LDPE blended, produce flexible container pack for liquids film at little three-layer co-extruded unit.

Described little three-layer co-extruded unit is three-layer co-extruded equipment, extruder draw ratio 30-35, die gap 1.5-3.5mm.

Described olefines special elastomer, the ratio of quality and the number of copies of mLLDPE and LDPE are 20-30:50-60:10-20.

Described temperature: 175 ~ 220 DEG C; Extruded velocity: main frame speed 25Hz, hauling speed 11m/cin.

The invention has the beneficial effects as follows: packaging film tensile strength, puncture resistant, high extensibility and rubbing property, resistance to bending performance significantly improve, the security that liquid bag film is used obviously improves, make in transportation (particularly low temperature, adverse circumstances) that the accidents such as brittle seepage punctures be less likely to occur, virtually reduce cost of transportation, also can not cause environmental pollution because of material loss, transportation safety coefficient increases simultaneously.
