Abstract
The utility model relates to a micropore ventilating film bag, which is provided with a bag body formed by folding a plastic film through thermally bonding. The bag body is provided with a bottom sealing edge, a lateral sealing edge and a top sealing edge; a feed opening and a gas outlet channel are formed on the lateral sealing edge; and the plastic film is provided with a plurality of sub-nano one-way ventilation micropores only allowing gas to be exhausted from the interior. The micropore ventilation film bag disclosed by the utility model has novel concept and is provided with the one-way micropores and the labyrinth type gas outlet channel. In addition, the micropore ventilating film bag achieves one-way ventilation and water-tightness and meets the requirements for package and storage of medicines or chemicals.
Description
Technical field
The utility model relates to pharmaceutical pack bag technique field, and especially a kind of micro-porous permeable bag film has the fluid-tight characteristic of one-way ventilating.
Background technology
Many medicines or chemical are the crystalline solid shape, and packaging and storing needs a kind of one-way ventilating waterproof bag, and a kind of common method of filling crystalline solid shape material in the bag is: by windstream crystalline solid is transported in the bag, after filling finishes sack is sealed.This just means in the bag after the filling also to comprise a large amount of air except that the crystallization solid filler, makes sack be spherical, and moisture in the residual air and oxygen etc. are understood the quality that influence medicine or chemical.
The packaging bag of present existing medicine or chemical is kraft compounded woven bag, and it is good to have intensity, waterproof and dampproof characteristics.But do not possess ventilative characteristics, gas inside can't be discharged, and will influence the quality of internal storage thing.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of micro-porous permeable bag film is provided, solve the existing sir-tight problem of kraft compounded woven bag, reach the fluid-tight purpose of one-way ventilating.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of micro-porous permeable bag film, has the bag that the folding after heat of plastic film is bonded, described bag has bottom edge sealing, sidepiece edge sealing and top edge sealing, described sidepiece edge sealing is provided with inlet point and outlet passageway, and described plastic film is provided with a plurality of Subnano-class one-way ventilating micropores that gas is come out internally.
Further, solid firmly for making bag film, described plastic film is a duplicature.
Further, for making things convenient for the can material, described inlet point is arranged near top edge sealing one side.
Further, the venting needs when satisfying fill material prevent that simultaneously material from leaking outside, and described outlet passageway is the labyrinth passage that prevents that weighting material from leaking outside, labyrinth channel import and bag internal communication, and the labyrinth channel outlet is in communication with the outside.
Further, realize better venting, offer a plurality of air gates on the plastic film at the outlet passageway position of described sidepiece edge sealing.
The beneficial effects of the utility model are, micro-porous permeable bag film of the present utility model is novel, is provided with unidirectional micropore and labyrinth type outlet passageway, and it is waterproof to reach one-way ventilating, satisfies the packaging and storing requirement of medicine or chemical.
