A waterproof paper bag made of paper and a method of forming same wherein at least one side the paper has been coated with a waterproof substance. The waterproof paper bag is manufactured from a sheet of paper which has been coated with a waterproof substance so that at least an inside of the paper bag is coated with the waterproof substance, such as a biodegradable resin, or wax. A piece of waterproof paper is then cut from the sheet and is folded and a flat bottom paper bag with the waterproof coating on an inside of the bag.

The present invention relates to a method for producing microbial probiotic biofilms and their uses in the biomedical, industrial, food and environmental field.

The present invention discloses a vacuum storage bag and a preparation method thereof. The vacuum storage bag comprises a bag body, which is equipped with an extraction valve and a sealing zipper; the bag body is composed of an inner film layer and an outer film layer by glue laminating, a blocking layer is arranged on the surface of the inner film layer; and the outer film layer is made of cloth. The vacuum storage bag of the present invention is made of cloth and PE film. The cloth is soft and folding, thick and wear-resistant, not easy to be brittle, and has long service life. In addition, there are many types of cloth and PE film for preparing the vacuum storage bag prepared in this application, which can be selected according to needs, so that the vacuum storage bag prepared has a wider scope of application.

A packaging container comprises a laminated sheet where at least a substrate, a barrier layer and a sealant layer are laminated together in this order, and the laminated sheet has a stiffness of 1.01 [mN.Math.m] or less measured by a Taber stiffness tester method in accordance with JIS-P8125.

This invention relates to a paper bag for bulk material such as cement, gypsum, granular material, animal feed or the like, with a bottom and with an upper part opposite the bottom, wherein bottom and/or upper part are folded and glued by closing up the side parts around side fold lines, in particular in the form of a cross or block bottom, wherein for gluing the side parts at least one gluing or bonding agent activatable after the application is provided, which is applied continuously at least from a side fold line up to at least the opposite side fold line of the side parts.

Described is a manufacturing a non-rigid container, the method including one or more of the following steps: coating a surface of a fabric with a water-based adhesive; leaving the product to cure for a predetermined period of time; temporarily adhering a paper to said adhesive surface of said fabric in a heat fusing press; cutting one or more required pattern pieces; stitching said one or more patters pieces together in a desired fashion; and coating said material with a hydrophobic coating.

A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

A thermoplastic bag includes structures that direct liquid away from areas of the bag more susceptible to failure and leaking. For example, one or more implementations include seals that direct liquid introduced into the bag away from corners of the bag. Additionally, one or more implementations include an insert positioned within the bag between the liquid directing structures such that the liquid directing structures direct liquid to the insert. In one or more implementations, the insert comprises an absorbent material. Thus, the liquid directing structures can direct liquid to a liquid absorbing insert.

The present invention relates to a band (1) that can be stored in reel format, which has areas coated by a thermally-activatable adhesive material (2) following a coating pattern (3) that is repeated along the band with at least two main transversal strips (5a, 5b) that extend between two longitudinal edges (1c) of the band and that include areas (21) coated with a grammage of thermally-activatable adhesive material between 35 and 130 gr/m.sup.2. A specific use of the band (1) is for making mesh bags (10) and in particular to close a portion of a tubular mesh (11) by interleaving said mesh portion between two coinciding portions of the same or of two bands (1, 1) and with respective main transversal strips (5a, 5a) of the coating pattern (3) towards the mesh; applying pressure; and providing heat.

Insulated packaging is provided including an inner substrate and an outer substrate attached to the inner substrate to form an air gap therebetween. An expandable material including expandable microspheres is provided with the expandable material disposed between the inner substrate and the outer substrate. An adhesive material different than the expandable material is disposed between the inner substrate and the outer substrate to attach the inner substrate to the outer substrate. A method for forming the insulated packaging is also provided.
