KRAFT SACKS USED TO STORE INDUSTRIAL-PURPOSE DUST AND GRANULE PRODUCTS

Abstract

A kraft sack is disclosed for products to be packed and stored in dust and granule forms such as chemical, food, mine, construction and building industry products. The kraft sack was manufactured to prevent from possible odour transition and humidity creation from and into package inside and outside of dust and granule raw materials, and provides protection thereof in order to maintain physical and chemical features of product against interior and exterior factors, against dusting that could occur during evacuation of air through perforation holes over kraft sacks during process of filling the kraft sack.

Claims

1. kraft sack for both single layer and multilayer packages comprising an exterior layer of sack comprising Kraft Paper such as Kraft paper with rapid air permeability, Kraft Paper with PE Lamination, Kraft Paper with Aluminium Folio, and for use in multilayer packages, comprising an interior layer of sack comprising kraft paper, such as Kraft paper with rapid air permeability, PE (hdpe, ldpe, mdpe, pp etc.), Kraft Paper with PE Lamination, Kraft paper with Aluminium Folio.

2. The kraft sack of claim 1, characterised to employ, possess an air evacuation part that is employed at layer or layers over space located at the part of lower base or upper base on inlet to fill product.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0020] FIG. 1—General appearance of product of invention subject.

[0021] FIG. 2—Detailed appearance of subject product of invention.

[0022] Parts appeared on the figure are separately enumerated, considerations of such numbers were provided as follows: [0023] (1) Inlet to Fill Product [0024] (2) Air Outlet/Evacuation Section [0025] (3) Lower and Upper Bases [0026] (4) Sack exterior layer consisting of Kraft paper (All kind of Kraft paper is able to apply.), Kraft paper with rapid air permeability, Kraft Paper with PE Lamination, Kraft Paper with Aluminium Folio (are able to use this layer at both single layer and multilayer sacks.) [0027] (5) Sack interior layer consisting of Kraft paper (All kind of Kraft paper is able to apply.), Kraft paper with rapid air permeability, Kraft Paper with PE (hdpe, ldpe, mdpe, pp etc.), PE Lamination, Kraft Paper with Aluminium Folio (are able to use at only multilayer sacks.)

DETAILED DESCRIPTION OF THE INVENTION

[0028] Positioning as set out below may be made within 1-6 layers employed by the package of the present invention.

[0029] Layer 1 in sacks with 1 layer consists of only kraft with polyethylene lamination, Kraft with aluminium folio and similar items.

[0030] In other layers, at the most exterior layer, there is employed Kraft Paper/Kraft paper with rapid air permeability/ paper with PE (polyethylene) lamination/Kraft paper with Aluminium lamination, which may be positioned at anywhere.

[0031] At layer 2-6, there is employed paper with PE Lamination/Kraft paper/Kraft paper with rapid air permeability/PE and its varieties (hdpe, ldpe, mdpe, pp etc.)/aluminium folio or paper with aluminium folio, which may be positioned anywhere,

[0032] Such layers other than them consist of all range of Kraft papers.

[0033] Locations and positions of papers may vary.

[0034] Air outlet section (2) positions at the layer or layers over the space existing at lower base where inlet to fill product (1) located or at upper base (3).

[0035] Within the frame of such fundamental concepts, it is possible to develop various practices relevant with invention subject of “progressions made to kraft sacks that are used to preserve industrial-purpose dust and granule product”, and the invention may not be limited to samples as set out here and it is basically as set out in the claims.
