Benefits of technology

[0037]Advantageously the hydrophobic biodegradable material can be preferentially placed in certain locations across the bag or within in the case of multiple ply bags to offer additional fu

Problems solved by technology

While it is possible to transport such product in bulk form through the use of large containers and hoppers, this method of delivery is inappropriate for more conventional consumers and trades people who require a more limited amount, often to confined locations where bulk delivery would make it difficult to access and deposit.
This then presents the opportunity that moisture could permeate or infiltrate its way through the porous paper thus contaminating the bagged dry particulate.
Nonetheless the introduction of the synthetic polymer and/or plastic based liners to these kinds of high density porosity papers has led to its own problems in that the recyclability of such bags has now become quite restricti

Example

[0043]FIGS. 1A and 1B show a preferred embodiment of this invention wherein the recyclable packaging container is a bag (14).

[0044]The bag (14) includes an outer ply of high density porous paper (16) and an inner ply of high density porous paper (18).

[0045]On the external surface (23) of the inner ply of high density porous paper (18) the hydrophobic biodegradable material (20) has adhered to the external surface (23) as droplets (19).

[0046]In between these droplets (19) are a series of spacings (21).

[0047]While not shown in the illustrations, when the contents of the bag (22) were received during filling, as the contents (22) are for the most part dry powders, particulate material, aggregates of cement and so forth it is very much a fluid process in the bagging of such material.

[0048]Therefore the bag (14) must have a degree of aeration otherwise during the filling process of the contents (22) into the bag (14) the dust of the product being bagged becomes a significant hazard.

Abstract

A recyclable bag for dry based powders, grains, particulates or aggregates having a minimum single ply of high-density porous paper adapted to be foldably configure into a sealable bag shape wherein at least one ply of high density porosity paper has an adhered layer of a hydrophobic biodegradable material on an external and/or internal side wherein the adhered layer of hydrophobic biodegradable material includes a series of holes, spacing and/or slots within or around the hydrophobic biodegradable material to allow air to pass there through for aeration of the bag during filling of the bag.

Description

FIELD OF THE INVENTION[0001]This invention relates to a new unique potentially recyclable high-density porous paper-based packaging container used in the bagging of dry based powders, grains, particulates and aggregates.[0002]More particularly this invention relates to a high-density porous paper-based packaging container that not only can be suitable for recycling but also inherently adapted to offer adequate protection to achieve moisture proofing of the bag in order to protect the contents therein without the use of a conventional synthetic polymer and / or plastic based liners.BACKGROUND OF THE INVENTION[0003]The person skilled in the art would be familiar with a range of substantially dry based powders, grains, particulates and aggregates that for the most part are bagged using high density porous paper so that the product can be sold conveniently to members of the purchasing public in various hardware or trade stores across the country.[0004]The bagging of the product is require...
