Abstract

The utility model provides a cement package bag to prevent cement from being affected with damp to deteriorate, particularly prevent the cement from being affected with damp to deteriorate in long-distance marine transportation process. The cement package bag comprises an outer layer bag body and an inner layer, wherein the outer layer bag body can be any package bag body with certain strength, such as a paper bag or a braided bag, and can directly hold a plurality of small bags of cement or bulk cement. The inner layer can hold a plurality of small bags of cement or bulk cement. A plastic film layer can be any common plastic film layer, such as a polypropylene layer, a polythene layer or a polyvinyl chloride layer. Preferably, the plastic film layer of the inner layer is the 0.00005-0.5 gram polypropylene layer with a thickness of 1-1000 g/m<2>. The cement package bag can be a large package bag with an opening structure, which is convenient to hold the small bags of cement or the bulk cement. The cement package bag provided by the utility model can ensure the guarantee life of the cement reaches over six months, and is particularly suitable for the package of long-distance shipped cement.

Description

Cement package bags

Technical field

The utility model relates to a kind of cement package bags.

Background technology

Cement is the important building materials of using always, is Powdered, after water mixes, can become hard Shi Zhuanti by the plasticity slurry through physical and chemical process.Cement package bags commonly used is woven bag or paper bag, this bag can only guarantee that cement never degenerated in 3 months, if the time is long again, and the cement sclerosis of will luming owing to making moist in the bag, particularly will be through the cement of long long-distance ocean freight, with regard to easier becoming damp and rotten.

The utility model content

In order to prevent that cement from becoming damp and rotten, particularly in order to prevent that cement from becoming damp and rotten in long-distance ocean freight, the utility model provides a kind of cement package bags.

The cement package bags that the utility model provides comprises outer bag and inner plastic thin layer.Described inner plastic thin layer plays moisture-proof role as the inner bag of described cement package bags, and the number of plies of described inner plastic thin layer is unrestricted, can also can be multilayer for one deck.

Described outer bag can for example can be paper bag or woven bag for having any packing bag of certain intensity.Described inner plastic thin layer can be any plastic film layers commonly used, for example can be polypropylene layer, polyethylene layer or polyvinyl chloride layer.Preferably, described inner plastic thin layer is the polypropylene screen of 0.1-1000 silk, and thickness is 1-1000g/m ²

Described inner plastic thin layer can be for being combined in the coating on the described outer bag.Described outer bag and described inner plastic thin layer also can be bonded together or thermoplastic is bonded together by adhesives.Described outer bag and described inner plastic thin layer also can combine by the mode that an end is sewed up, and the other end is uncovered.Described outer bag and described inner plastic thin layer also can directly be nested together, one section sealing, and an end is uncovered.

Described cement package bags can be different shape, for example sealing end has only carried out the simple bag of straight line closure, also can be for having the bag of various three-dimensional shapes, for example cylindric, oval column, rectangular-shaped etc., closing end then is respectively garden, ellipse, rectangle etc.

Described cement package bags can be the big packaging bag of all size, it for example is the 200-2500KG level, the cement of the pouch-packaged of many bags of 50KG levels can be packed into wherein, the pouch-packaged of described 50KG level can have plastic film layers, also can be the Portland cement bag of no plastic film layers, after loading finishes, closed opening end, thus in bulk or many bags of cement are enclosed in the described big packaging bag.In the process of sea-freight, can play the damp proof insulation effect well like this.

Above-mentioned any cement package bags that uses the utility model to provide can both make the shelf-life of cement reach more than 6 months, and the cement package bags that the utility model provides is highly suitable for the packing of long sea voyage cement.

Description of drawings

The scheme drawing of a kind of cement package bags that Fig. 1 provides for the utility model;

The scheme drawing of the another kind of cement package bags that Fig. 2 provides for the utility model.

Among the figure:

The outer bag of 1-; 2-inner plastic thin layer; The 3-suture site; 4-is uncovered.

The specific embodiment

Also in conjunction with the accompanying drawings the utility model is further described below by specific embodiment.

Fig. 1 has represented a kind of cement package bags, and this cement package bags comprises outer bag 1 and inner plastic thin layer 2, and outer bag 1 is a woven bag.Inner plastic thin layer 2 is for being combined in the polypropylene screen of the 0.1-1000 silk on the outer bag 1, and thickness is 1-1000g/m ²

Fig. 2 has represented another kind of cement package bags, this cement package bags comprises outer bag 1 and inner plastic thin layer 2, outer bag 1 is a woven bag, inner plastic thin layer 2 is a polypropylene film, outer bag 1 and inner plastic thin layer 23 have carried out closure at the position, leave uncovered 4 usefulness that are used to pack into cement.

Above-described cement package bags can also can be the big packaging bag of 200-2500KG level for the pouch body, as big bag a plurality of little bags of can packing into, in the process of sea-freight, can play better damp proof insulation effect like this, pack into behind a plurality of cement bags, encapsulation is promptly finished in the opening end sealing.
