Description

A kind of fungi-proofing packaging bag

Technical field

The utility model relates to packaging field, in particular to a kind of fungi-proofing packaging bag increases anti-between bag body and bag mouth Bacterium layer and packaged material is filling without bag mouth, bag mouth is while filling by press seal.

Background technique

Packaging bag is a kind of packing container for food, beverage etc. common in daily life, due to its is low in cost, It is easy to use, therefore be usually used in packing as the small dimension of many commodity.Because it is used to contain food, the convenience that people are used for Property, anti fouling performance all have higher requirement.Existing food pack, by taking flour paste bag etc. as an example, be in the past it is disposable packed, That is instant bagged, and it is just then bad when there is residue save, lose and waste, therefore have at present and install this packaging bag additional Bag mouth, not only conveniently took, but also can quantitatively use, and the remaining lid that screws is saved, it is very easy to use to remain next time.But This packaging bag with marsupial mouth is in processing filling by bag mouth, since filling process greatly reduces the shelf-life of food, and And since the protrusion effect of resist compression of mouth is bad, especially for have air-drop be unfavorable for ensureing when needing it is safe and healthy.

Summary of the invention

To solve the above-mentioned problems first purpose of the utility model be to provide one kind prevent it is filling from bag mouth and by Pollution and the extraneous compressing of guarantee bag mouth reduction and dust-proof fungi-proofing packaging bag in air-drop.

The technique that second purpose of the utility model is to provide a kind of aseptic packaging.

A kind of fungi-proofing packaging bag that in order to achieve the above purposes, the technical solution adopted by the utility model is:, including bag body, bag Mouth, the bag body of bag mouth lower part is interior to be equipped with fungi-proofing sealing pressing layer.

The fungi-proofing sealing pressing layer can be pressurized from bottom to top bursting outside bag body and a bag inner package is made to flow to bag mouth.

The fungi-proofing sealing pressing layer is shaped form.

The shaped form is linear or arc or triangle.

The bag mouth includes with externally threaded stationary exit portion and with internal thread outer cover.

The bag mouth includes with internal thread stationary exit and screwing in upper cover of the stationary exit with inner core, the inner core In being communicated for externally threaded cavity and lower end is with top taper, external screw thread cavity wall is equipped with interior core cavity Core aperture.

The length of the inner core is can the fungi-proofing sealing pressing layer of bursting when screwing in downwards.

The outside of bag body is arranged in the bag mouth.

It is equipped with the seal protection film with bag body integrally connected outside the bag mouth, and is equipped with tearing notch in bag mouth position.

A kind of manufacturing process of fungi-proofing packaging bag, it is characterized in that: including the following steps:

Step 1 is sterilized with dioxygen washing film；

Step 2, film enter bag shaper molding；

Step 3 seals fungi-proofing line；

Step 4 is pressed into bag mouth, while envelope bottom outside fungi-proofing line；

Step 5, material enter a bag press seal bag side from side；

Step 6, cutting, takes the subpackage bag of packing material；

Step 7 repeats step 1 to 6, and batch obtains the subpackage bag of packing material.

The beneficial effects of the utility model are: bag inner package storage safely, extend shelf life and shelf-life, reduce The commercially available link because of period continuous undercarriage, reduces selling cost；And resistance to compression can drop again, be suitble to war and use of relieving the people in stricken areas.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Fig. 1 to 7, a kind of fungi-proofing packaging bag, including bag body, bag mouth, bag mouth be arranged in bag body outside or with bag Body is provided at an outer portion with protective film together, is equipped with fungi-proofing sealing pressing layer 300 in the bag body 100 of 200 lower part of bag mouth.Fungi-proofing sealing pressure Closing layer 300 can make internal fluid flow to bag mouth by the extruding bursting outside bag body from bottom to top；Fungi-proofing sealing pressing layer 300 be various curved shapes, the upward arc such as top.

Bag mouth includes unscrewing outer cover with externally threaded stationary exit portion 700 and with internal thread outer cover, working as compressive zone Fungi-proofing sealant smoothly can be racked along top when inner package, packing material is flowed out through bag mouth.

Bag mouth can also be with internal thread stationary exit 700 and screw in stationary exit 700 with the upper of inner core 600 Lid, inner core 600 is with externally threaded cavity and lower end is with top taper, and external screw thread cavity wall is equipped with and inner core The inner core aperture 800 that chamber communicates, the length of inner core 600 is can the fungi-proofing sealing pressing layer 300 of bursting when screwing in downwards.When using Along tearing notch tear fracture upper end, expose inner core, rotary inner core, the fungi-proofing layer of bursting opens heart when the aperture of inner core enters in liquid Upper cover can guide to liquid.Inner core is reversely rotated when not drinking, buckling upper cover both can be reserved for liquid in bag.

Fungi-proofing packaging bag manufacturing process, includes the following steps: step 1, is sterilized with dioxygen washing film；Step 2, film enter Bag shaper molding；Step 3 seals fungi-proofing layer；Step 4 is pressed into bag mouth, while envelope bottom outside fungi-proofing line；Step 5, material Enter a bag press seal bag side from side；Step 6, cutting obtain pouch packing packing material；Step 7, repeats step 1 to 6, batch Obtain packing packing material.

As shown in figure 8, packaging material is sterilized by 2 dioxygen washing films, enter 4 bag shapers by 3 film feeding parts.Film passes through Former becomes the shape of packaging bag.After carrying out the fungi-proofing layer of 6 envelopes, bag mouth enters packaging bag by 7 conveyers.Film is in 9 tractions Under roller traction, pressure mouth, back cover are carried out to packaging bag to next station 8.Packaging bag continue under to blanking behind 10 envelope sides.Packaging bag It continues traveling downwardly and is cut off by cutter.A process is completed to this.

During bag making, the jail of pollution and bag mouth and packaging bag sealing when fungi-proofing weak link is to send bag mouth The reliability of degree.For this purpose, we packaging bag design together fungi-proofing layer, that is, ensure that sack to the sealing of material again with bag mouth Separation is come absolutely, can be extended the shelf life in this way.When in use, as long as fungi-proofing line, which firmly can be opened, once crowded material reaches bag Mouth.
