A sack for realising civil engineering works, including a sack structure with two main faces defined by two respective equal main areas of cloth that are joined over most of their periphery. The main areas of cloth define an opening for introducing filling material into the sack structure when in use. The sack includes at least one area of protective cloth whose resistance characteristics differ from the main areas of cloth. The area of protective cloth is fastened to the outside of the sack structure so as to substantially cover a single main face thereof.

A crop storage bag (1) made is of a high-strength textile (7) material which is extrusion-coated or laminated with a multilayer film (8) that comprises an insecticidal layer (9) in addition to a hermetic layer (10) which prevents oxygen from entering the bag. This oxygen barrier suffocates the insects inside the bag, and the insecticide kills insects that try to bore through the bag.

A biodegradable bag and method of using same for storing and transporting ice chunks, the method including enclosing about 5 lbs to about 50 lbs of ice chunks within a 100% knitted, cotton yarn bag, placing the bag within a freezer for maintaining the ice chunks below at least 0 C., storing the bag containing the ice chunks in the freezer and transporting the bag containing the ice chunks in a freezer compartment of a motor vehicle to a retail location for purchase by an end-user.

In one method, a piece of nonwoven PET or PP fabric is formed into a tote bag using a bag forming device. Seams of the tote bag are ultrasonically welded using an ultrasonic bag welding device. The ultrasonic bag welding device includes at least one sonotrode. In another method, BOPP film is received and a full-color graphic is printed on the BOPP film for each tote bag using a printer. The printed BOPP film is received from the printer and nonwoven PP or PET fabric is received from a roll of nonwoven PP or PET fabric using a laminator. The printed BOPP film is laminated to the nonwoven PP or PET fabric. The printed BOPP film laminated to nonwoven PP or PET fabric is received from the laminator and a finished version of each tote bag is produced using an ultrasonic bag welding device.

The present invention relates to bag- or sack-like packaging provided with a body (10) formed by a film of polymeric material and provided with at least one layer (20) composed at least in part of raffia, the layer (20) being welded to the body (10), the packaging thus promoting easy, efficient recycling, and improved palletization and storage, and allowing the automation of the manufacturing process.

A cotton-based single use grocery bag for carrying groceries or other items. The single use grocery bag is also used for cleaning furniture, cleaning counter tops, washing dishes, etc.

A selectively openable and closable, outdoor storage bag that is at least water-resistant includes a body portion made of a flexible, waterproof, bag material, the bag material comprising a plurality of waterproof welded seams that define a predetermined shape of the body portion and an opening, the body portion defining an interior space within the body portion; a closure mechanism joined to the body portion by a welded seam proximate a periphery of the opening, the closure mechanism configured to selectively open and close the opening and provide a seal that is at least water-resistant when the opening is closed; a flap of the bag material that extends from the body portion and covers the closure mechanism; and a plurality of anchor points attached to an exterior surface of the body portion, wherein the body portion of the bag is waterproof and the seal is at least water-resistant.

A woven laminated plastic bag having a weakened portion is provided. The weakened portion is generally defined by a plurality of perforations in the bag. In various aspects the bag can be fabricated from woven polypropylene and/or polyethylene layer which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.
