Abstract
The utility model discloses a plastic package bag which can be sealed repeatedly and is firm. The utility model integrates the advantages of one-step heat-pressing type sealing and snap fastener type package bags. By improving a traditional snap fastener, the utility model solves the technical problems that traditional snap fastener sealing can not be used on mechanical packaging production lines. The utility model can firstly prefabricate the snap fastener and fix the snap fastener at the inner side of a package bag, and then the utility model can be sealed by heat-pressing so as to attain the purpose of sealing, firm package bag and repeatable sealing.
Description
The utility model relates to a kind of package packing supplies, is characterized in packing tight, solid and can repeats repeatedly sealing, and can be fit to the production of mechanical packaging conveyor line.
When sealing, existing plastic packaging bag can only do that hot pressing is disposable seals on the mechanization conveyor line.Though thisly seal tightly solidly, in use, seal and to seal again again after taking apart, to the preservation of article, place, carry and bring inconvenience.Other has a kind of plastic bag that has snap fastener that repeats to seal, because seaming is to be formed by two kinds of different unit constructions of structure, and incompatible production continuously on the mechanical packaging conveyor line, sealing bags, opening easily effectively.
Task of the present utility model provides a kind of suitable mechanization flowing water to produce to people, and is both tightly solid, again the plastic bag that can repeat to seal.
The utility model has adopted dual mode simultaneously when plastic bag sealing, a kind of is the disposable thermal pressure seal mouth, and this tightness of sealing is good, and is solid firm.In addition, the parallel position of face within it, a bonding plastics snap fastener bar that has emboss pit.This seaming bar improves original seaming bar, makes it be applicable to the production of mechanization conveyor line.Such packaging bag, good airproof performance solidly firmly seals that commodity once too many or too much for use in the bag of back if tear first road, and also available plastics snap fastener repeatedly seals repeatedly, and such improvement had both made things convenient for the customer, and the wave that has reduced commodity again gives up.
Task of the present utility model is finished by following mode: go out to have the flat, plastic snap fastener bar of twice tongue with groove, the arbitrarily interlock of the emboss pit of two snap fastener bars with plastics-production earlier.When the mechanization conveyor line was packed, when packaging bag also was in flattened state, the plastic strip correspondence that will have an emboss pit with the mode of bonding or pressing at the sack place was fixed on the sack, and then folds in the usual way, feeds, seals.Compare with existing plastic bag packaging mode, the utility model has following advantage:
1. the disposable seal package bag of existing heat pressing type when tear seal after, in the bag commodity if too many or too much for use and can not seal as secondary, be not easy to commodity preservation, place and carry.The utility model is because many one plastics seamings, and packaging bag can repeatedly effectively be sealed voluntarily.
2. existing snap fastener formula plastic bag has only one activity to seal, and its leak tightness, impact resistance are poor, commodity safety inadequately in the bag.And snap fastener is made of two kinds of different structures, and manufacture craft is complicated, is not suitable for continuously, flowing water production.The utility model is transformed by traditional snap fastener formula is sealed, and makes its designs simplification, is suitable for large-scale production.
3. existing two kinds of plastic bags respectively have merits and faults, and the utility model improves two kinds of sealing modes, and combines, and make that packaging bag both sealed, solid, safety, can repeat repeated use again.

Fig. 2 is the utility model mounted package scheme drawing.
Fig. 3 is the lateral plan of the utility model fastening, sealing state.
Fig. 4 is the utility model snap fastener formula strip of paper used for sealing front elevation.
Fig. 5 is the utility model snap fastener formula strip of paper used for sealing side-looking moulding figure.
Snap fastener formula strip of paper used for sealing 2 is housed and heat pressing type seals 3 with reference to accompanying drawing, plastic packaging bag 1 opening part.Snap fastener formula strip of paper used for sealing 2 is that the independent plastics of making are rectangular, twice convex tendon 4 is arranged with groove 5 on the mouth biting type strip of paper used for sealing 2, and convex tendon 4 both sides are shirt rims 6, and convex tendon 4 is can image pattern 3 such mutual interlocks with groove 5.
Elder generation's mouth biting type strip of paper used for sealing 2 as Fig. 5 made of plastic during making.When plastic bag 1 launches such as Fig. 2 opening part paste or mouth biting type sealing strip 2 of hot pressing, be folded mechanically close up make a bag shape to put into article to be installed after the reusable heat pressure type seal 3 sealing sacks and get final product.The tear initiation heat pressing type seals 3 during use, draws back biting connecions and seals 2 and can take out products to be packaged, can make its interlock by tight mouth biting type strip of paper used for sealing 2 as once toing many or too much for use, and can reach repeatedly to repeat the effect of sealing.
Claims (3)
1, a kind of by plastic packaging bag 1, plastics seaming strip of paper used for sealing 2, disposable thermal pressure seal mouth 3, convex tendon 4, groove 5, sealing, the solid plastic packaging bag that repeats to seal of compositions such as shirt rim 6 is characterized in that opening part at plastic packaging bag one heat pressing type that be arranged in parallel seals with the snap fastener formula and seal.
2,, it is characterized in that plastics snap fastener strip of paper used for sealing 2 is that to fold the prefabricated plastics of the groove 5 that forms and two shirt rims 6 forming by 4, one of two parallel convex tendons rectangular by the plastic bag of claim 1 regulation.
3, the plastic packaging bag by claim 1 regulation is characterized in that plastics seaming strip of paper used for sealing 2 is fixed on the opening of plastic packaging bag 1, and strip of paper used for sealing 2 shapes on opening both sides are identical, can be engaged.
