Abstract

The utility model relates to a ribbed paper bag with a flat bottom valve port, which belongs to a packaging bag. The existing flour packaging bags adopt white cloth bags for a plurality of years, which waste cotton cloths and have the disadvantages of flour is easily hygroscopic and becomes mildewed. In addition, the flying of the flour easily results in waste and pollution when carrying. The improved woven bags, plastic braided bags, multi-layer paper bags also have deficiencies. The ribbed paper bag with a flat bottom valve port is characterized in that the internal and the external layers of the clipping ribs are stuck with rib gauze. The utility model has the advantages of simple structure, paper saving, low cost, high strength, proper air permeation, sanitation, anti-corrosion, mildew proof, not brittle and hard, no poison, no taste, no pollution, recoverable property, and piling without slipping. The ribbed paper bag with a flat bottom valve port can be made into various specifications and is mainly used for shipping flour and grain and also be used for shipping chemical materials, fertilizer, cement, etc.

Description

Flat-bottom valve port ribbed paper bag

The utility model belongs to packaging bag, particularly is applied to the packaging bag of grain (flour).

White cloth bag is continued to use in existing grain (flour) packaging bag for many years always, the waste cotton, and the easy moisture absorption mildew of flour, flour flies upward and causes waste and pollution during carrying; Or with woven bag, mould and compile bag and pack flour, no bursting strength, flour are also easily mould to go bad, and grinds hand during carrying, pile is sent out cunning, can not reclaim contaminated environment; Or use the multiwall kraft packaging bag, the cost height is wasted a large amount of paper.

The purpose of this utility model provides a kind of flat-bottom valve port ribbed paper bag, this flat-bottom valve port paper bag is that the folder muscle is bonded with the muscle yarn and makes between two layers of paper, be used to load and transport flour, seed, chemical fertilizer, cement, mineral products etc., have that good air permeability is suitable, intensity is high, breakage rate is low, no leak, be convenient to characteristics such as accumulating.

The technical solution of the utility model is, this paper bag is made the flat-bottom valve port paper bag, is characterized in that the folder muscle is bonded with the muscle yarn between the internal layer of paper bag and the skin.

This effective reinforcement yarn can be muscles along the regular meridians yarn and latitude muscle yarn.

According to requirements such as the article of packaging and weight, can suitably select parameters such as the number of muscles along the regular meridians yarn, latitude muscle yarn, mutual spacing and angle for use, to form the series package bag product of different size.Sometimes the muscles along the regular meridians line can be not necessarily vertical mutually with latitude muscle yarn.

As grain (flour) packaging bag, the internal layer of this paper bag and skin can be selected craft paper or other sack kraft papers for use; Muscles along the regular meridians yarn and latitude muscle yarn can be selected chemical synthetic fiber yarn, mixed yarn, the dimity, glass fiber yarn etc. for use; Adhesion agent should be selected for use and meet nontoxic, the free from extraneous odour of shipment food, requirement such as pollution-free.

This flat-bottom valve port ribbed paper bag, there is distinguishing mark at the place at the flat bottom bags valve port, picks up at the bottom of with bag with hand during filling, and valve port just launches naturally, packs into bottle placer discharging mouth and gets final product.Flat bottom bags is convenient to pile in transportation and keeping process.This paper bag is simple in structure, has saved paper, and cost is low, and the intensity height is suitably ventilative, and the anticorrosion mildew-resistant of health is not crisp hard, nonpoisonous and tasteless, recyclable utilization.Make different size, mainly be applicable to shipment flour, grain, also can be used for loading and transporting chemical, feed, seed, chemical fertilizer, cement, mineral products etc., field of application is very extensive.

Accompanying drawing 1 is a structural representation of the present utility model.Fig. 2 is the A-A sectional structure scheme drawing of this packaging bag B face.Among the figure: 1 paper bag main body, 2 sacks, 3 skins, 4 internal layers, 5 muscles along the regular meridians yarns, 6 latitude muscle yarns, 7 adhesion agent are at the bottom of 8 bags.

Below in conjunction with accompanying drawing the utility model is further described.

The paper bag main body (1) of this ribbed paper bag with flat bottom, sack (2), the bag end (8) Identical with existing flat-bottom valve port bag, characteristics are internal layer (4) and outer (3) at this paper bag Between the folder muscle be bonded with muscles along the regular meridians yarn (5) and latitude muscle yarn (6).

When implementing this ribbed paper bag with flat bottom, available existing bag unit repacking or With folder muscle machine, between internal layer and skin, be evenly arranged muscles along the regular meridians yarn and latitude with adhesive The muscle yarn makes internal layer-muscles along the regular meridians yarn, latitude muscle yarn, adhesive-skin closely through roll extrusion afterwards Glue bond is integrated, beat the tube after make the flat-bottom valve port paper bag. Also can adopt other equipment and Method is made.

Embodiment: the utility model designer implements a kind of flat-bottom valve port ribbed paper bag that loads and transports flour, internal layer and skin are selected 80 gram GB craft papeies for use, muscles along the regular meridians yarn and latitude muscle yarn are selected 21 synthetic fiber yarns for use, this synthetic fiber yarn raw material sources are extensive, cost of manufacture is low, has intensity height, wear-resisting, light weight, acid and alkali-resistance, heat-resisting, withstanding corrosion on the performance, anti-ly damages by worms, characteristics such as anti-mould, good water absorption; It is the self-control food adhesion agent of primary raw material that adhesion agent is selected for use with the cornstarch, and this adhesion agent technology is simple, inexpensive, consumption is few, and fast drying is firmly sticking, nonpoisonous and tasteless pollution-free, craft paper and the equal porous of synthetic fiber yarn also closely are bonded together, and have enough intensity.According to the requirement of 25 kilograms of flour of shipment, muscles along the regular meridians yarn spacing is selected 1 centimetre for use, and 1.5 centimetres of latitude muscle yarn spacings are made wide 500 millimeters, high 720 millimeters flat-bottom valve port ribbed paper bag after the roll extrusion drying, and it is very good to be used to load and transport the flour effect.

Claims

1, flat-bottom valve port ribbed paper bag belongs to the flat-bottom valve port paper bag, it is characterized in that the folder muscle is bonded with the muscle yarn between the internal layer of paper bag and skin.

2, flat-bottom valve port ribbed paper bag as claimed in claim 1 is characterized in that said muscle yarn can be muscles along the regular meridians yarn and latitude muscle yarn.
