Abstract
The invention relates to a liquid packaging bag film for a flexible container, belonging to the field of packaging films for container transportation. The liquid packaging bag film for the flexible container is characterized by being prepared by blending a special olefin elastomer, mLLDPE (metallocene-linear low density polyethylene) and LDPE (low density polyethylene) and produced in a small three-layer coextrusion set. The tensile strength, puncture resistance, extensibility, flex durability and bending resistance of the liquid packaging bag film are greatly enhanced, the use safety of the liquid packaging bag film is obviously improved, the accidents such as embrittlement, leakage and puncture in transportation especially in low-temperature and severe environments can be avoided, the transportation cost is lowered invisibly, the environment pollution caused by material loss can be avoided, and the transportation safety coefficient is improved.
Description
Technical field
The present invention relates to a kind of flexible container and use the pack for liquids film, belong to the container transportation and use the packaging film field.
Background technology
In recent years, container is used widely as a kind of new model of plastic flexible package with liquid packaging film, and packaging film is used in the container transportation, and common packaging film content has: oily substance, plasticizer, pitch or the like liquid.Liquid flexible packaging made from plastic film is mainly polyethylene (PE) co-extrusion film on the market; But at use film bag seepage takes place firmly sometimes; Cause direct economic loss and some indirect economic loss thereof; So promptly caused loss of material, also can bring pollution simultaneously, brought very big inconvenience for container transport liquid material environment.
Summary of the invention
According to the deficiency of prior art, the technical problem that the present invention will solve is: provide a kind of flexible container to use the pack for liquids film, packaging film tensile strength, anti-puncture, flexibility, anti-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 to use the pack for liquids film; It is characterized in that with olefines special elastomer, mLLDPE and LDPE blend, produce flexible container at little three-layer co-extruded unit and use the pack for liquids film.
Described little three-layer co-extruded unit is three-layer co-extruded equipment, extruder draw ratio 30-35, die gap 1.5-3.5mm.
The ratio of quality and the number of copies of described olefines special elastomer, mLLDPE and LDPE is 20-30:50-60:10-20.
Described temperature: 175 ~ 220 ℃; Extruded velocity: main frame speed 25Hz, hauling speed 11m/cin.
The invention has the beneficial effects as follows: packaging film tensile strength, anti-puncture, high extensibility significantly improve with rubbing property, anti-bending performance; The security that liquid bag film is used obviously improves; Make that (particularly low temperature, adverse circumstances) are not easy to take place accidents such as the embrittlement seepage punctures in transportation; Reduced cost of transportation virtually, also can not cause environmental pollution because of material loss simultaneously, the transportation safety coefficient increases.
