Description

Nonwoven fabrics package bag and manufacture method thereof

Technical field

The present invention relates to a kind of packaging bag and manufacture method thereof, relate in particular to a kind ofly be applied to make tea, Baoshang, filtration fruit juice and decoct the nonwoven fabrics package bag and the manufacture method thereof in fields such as Chinese medicine.

Background technology

We often will use the juice of food and get rid of last residue in life, there are not a kind of the be exclusively used in convenience type that filters in the life as tealeaf residue, Chinese medicine slag etc., small-sized bag filter pack at present, people are with some stupid methods, directly juice is poured out, remaining residue is poured residue in refuse bag or the toilet into again in the final container, so not only has residue in the juice, and residue is unclean from container, also can stop up sewer.

Summary of the invention

In order to solve the problem of above-mentioned existence, the purpose of this invention is to provide a kind of nonwoven fabrics package bag of easier filtration juice.

Technical scheme of the present invention is achieved in that a kind of nonwoven fabrics package bag, comprises bag, the bag end and pkt. flap, bag, the bag end and pkt. flap are one, and bag divides two of front and back, two doublings in front and back, dual-side is joined together to form bag, the bottom is the bag end, and bag anter top outwards turns down, and dual-side is connected with the bag dual-side respectively, form outer pkt. flap, bag rear panel top inwardly turns down, and dual-side is connected with the bag dual-side respectively, forms the inner cap bag.

The described bag end, turn down in bag, and bag end dual-side is connected with the bag dual-side, and its vertical parting face is W shape.

The bag side and the bag end, pkt. flap are connected for the hot pressing mode with the bag side.

Interior pkt. flap is uneven in length with outer pkt. flap.

Another object of the present invention provides a kind of manufacture method of nonwoven fabrics package bag, may further comprise the steps:

1., get a nonwoven fabrics, it is folded to form forward and backward two;

2., from burst amount certain size respectively with forward and backward two respectively reflexed come, form the oblong that symmetrical folding line is arranged at the bottom;

3., measure the certain size folded outwards, measure certain size from the top of rear panel folding inward, and the centre of folded edge being inserted anter and rear panel from the top of anter; Form the oblong sack that only exposes front-sheet cover;

4., with forward and backward both sides capper hot pressing, it is all closed to form about one face and bottom surface, has only the packaging bag of top opening.

Compared with prior art, the invention has the beneficial effects as follows: this packaging bag can be removed residue easily, and is easy to use, and environmental protection.Manufacture method of the present invention is simple, and the packaging bag result of use of formation is better.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail, but not as a limitation of the invention.

As shown in Figure 1 and Figure 2, a kind of nonwoven fabrics package bag comprises bag 1, the bag end 3 and pkt. flap, bag 1, the bag end 3 and pkt. flap are one, 1 fen anter 6 of bag and rear panel 7, two doublings in front and back, dual-side is joined together to form bag 1, the bottom is the bag end 3, and bag 1 anter 6 tops outwards turn down, and dual-side is connected with bag 1 dual-side respectively, form outer pkt. flap 5, bag 1 rear panel 7 tops inwardly turn down, and dual-side is connected with bag 1 dual-side respectively, form inner cap bag 4.

The described bag end 3, turn down in bag 1, and the bag ends 3 dual-side is connected with bag 1 dual-side, and its vertical parting face is W shape.

Bag 1 side and the bag end 3, pkt. flap and bag 1 side are connected to form edge sealing 2 for the hot pressing mode.

A kind of manufacture method of nonwoven fabrics package bag may further comprise the steps:

1, gets the oblong nonwoven fabrics of a long 240mm of wide 90mm as shown in Figure 3, look out 115mm up and down to rolling well from one, form a page length, the anter 6 of another page weak point and the oblong of rear panel 7;

2, measure 2mm from burst to rear panel as shown in Figure 4 the rear panel reflexed is come, equally also measure the 2mm reflexed to the anter end and come, formed the shape that symmetrical fold is arranged at two of front and back and bottom;

3, measure the 35mm folded outwards from the top of anter as shown in Figure 5, measure 25mm from the top of rear panel folding inward, and the centre of folded edge being inserted anter 6 and rear panel 7; Form and only expose the oblong of a wide outside of 35mm

4, as Fig. 2 with the both sides of anter and rear panel capper hot pressing, it is all closed to form about one face and bottom surface, has only the packaging bag of top opening.

Using method:

For example tealeaves is put into bag, turn and cover sack, can use being exposed at the outer one deck cloth of sack.

To make tea is example: with above-mentioned way with tealeaves sack good seal, put into cup and infuse tea, can avoid drinking, the tealeaf residue in sack and the bag thereof can be thrown away in rubbish container afterwards into tealeaf residue, usual tealeaf residue is poured toilet into, then sewer pipe is easily stifled, or then tealeaf residue is unclean to pour sewage disposer into, and this product all can avoid above-mentioned situation to take place, and it is clean, health is easily handled, and environmental protection.

With fricassee is example: seasoning matter is placed in the bag good seal stewes with meat, not only do not have the seasoning matter slag in the dish, but also good-looking, it is also convenient to taste, easily handle, and environmental protection.
