Description

Bag and preparation method thereof in isolated cylinder
Technical field
The present invention relates to new packaging material and package constructions, are more particularly for built-in appearance in producing or living Such as bag in the isolated cylinder in cylinder, case in device, the fluid of storage splendid attire can be made not contact cylinder, need to completely cut off suitable for those Air, the flowing object for needing closed storing, abstaining from ingress of air, oxidation deterioration easily occurring, such as the easy oxygen of pure water, draft beer Change the storing of fluid easy to pollute.
Background technique
Currently, bag in well-known cylinder, such as chemical industry oil plant, majority are single layer, easy packaging bag, one usually will In the direct placing tube of packaging bag, fluid is placed into, fills with after rear tying lid lid again, easy air-dispersing material leakage is easily overflowed in transport, nothing Method contains food and drink etc., the hygienic requirements that the heat insulation effect to drink is not achieved, transports object, and sky is contacted when pouring out Gas, some readily oxidizable substances may ingress of air occur oxidation deterioration phenomenon, while there is also contain object cannot disposably put Out, enter air during releasing, bring bacterium, dust into etc., keep splendid attire object rotten, is unfavorable for mechanization filling, in cylinder in bag Discharge of materials is not clean, and appearance residual i.e. waste is again unhygienic, therefore there is an urgent need to develop built in a kind of not only applicable but also health Packaging bag is to meet the actual needs in people's life and production.
Summary of the invention
Disadvantages mentioned above can be overcome the purpose of the present invention is to provide a kind of, and there is structurally reasonable, sturdy and durable, replacement just Prompt, hygienic pollution-free, heat preservation does not radiate, integrates bag and production method in the hollow type cylinder of air-isolation and pollution sources, especially It is using MULTILAYER COMPOSITE, air and liquid object isolation structure packaging material, substantially increase bag flexibility in cylinder, durability, Heat insulation property and emptying effect, the built-in packaging bag, the fluid that storage can be made to contain do not contact cylinder, are especially applicable in Those need to completely cut off air, need it is closed storing, abstain from ingress of air, easily occur oxidation deterioration flowing object, as pure water, The storing of the oxidizable fluid easy to pollute such as draft beer is preferably to be used to produce, transport, store etc. to contain the hard of all kinds of liquids The built-in soft body packaging that matter case cylinder matches.
Bag is to constitute bag film by bag bottom, bag cylinder, sack etc. in isolated cylinder of the invention, the bag at least two tunic structures At gas chamber, object room, wherein formed between gas chamber, object room by film interval, gas chamber, object room can be partitioned into and row pattern by film Or phase shell-like, gas chamber, object room are respectively independent confined chamber, plenum roof is there are porting, and there are into row's object in object ceiling portion Mouthful, gas chamber porting can connect the directly filling liquids in air inlet rear cover top cover labyrinth as needed, object room with gas source and seal, can Vacuum filling does not contact gas and air, and bag in isolated cylinder built in above-mentioned composition, wherein two-layer film is nested into mutually indepedent Gas chamber, object room；Three-layer thin-film spacing side by side is at mutually independent gas chamber, object room；When object room, liquid need to be filled with, gas chamber according to Contain liquid needs air inlet or exhaust, appropriate carbon dioxide gas can be added when needing to liquid insulating, if you do not need to can Gas chamber air is emptied, to increase the amount of storage in cylinder；When object room, liquid need to be emptied, gas chamber is according to the needs of contained liquid Object room evacuation of liquid is assisted in air inlet, is effectively improved and is contained liquid storage and transportation quality and using quality, it is filling to realize mechanization Production, improves production efficiency.Can multi-layer structure design, increase the antiseepage coefficient of leakage；Twoport design is imported and exported, fluid, air are double Cell structure is not easy to make material ingress of air, and increases mass rate of emission, is conducive to mechanized operation；Emptying Rate height does not remain, not unrestrained Take；It is reusable, save the cost；Non-once discharges material, it is ensured that air does not enter in material bag.
Its production method is first to make film special, according to the equipment that bag film specification size chooses blown film, is chosen Screw extruder chooses the matching die that can meet specification requirement；Raw material chooses polyethylene: in order to guarantee the soft of bag in cylinder Soft, the raw material for making sack is chosen, and based on hp-ldpe, in order to reinforce the intensity of sack, can add part in right amount Hide illegally, metallocene linear polyethylene and Hi-fax, and means suitable sack certain stiffness can to add in right amount part low Press high density polyethylene (HDPE)；
