Full recycling environmental protection packaging structure and manufacturing method thereof

A full recycling environmental protection packaging structure and a manufacturing method thereof applied to express deliveries, postal services and logistics and made of a planar structure of paper. The packaging structure includes a first surface and a protecting layer overlapped on the first surface. The protecting layer includes at least one layer of liner which is a three-dimensional network structure formed by paper material being stretched after being die-cut. The planar structure is sealed edges thereof and an opening is reserved to form a bag body. The packaging structure of the present disclosure can overcome problems that kraft paper bubble bags or envelopes, and paper and plastics can't be separated and recycled to pollute environment in the prior art. At the same time, it can solve technical problems of dust pollution and poor air quality caused by using powdery and granular soft structures used as buffers.

A Hermetic, Insecticidal Food Storage Bag, Use of It and a Method for Its Production

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.

Apparatus and method of manufacturing open-mouth bags (2), comprising a storage device (3) with a supply (4) of bag film (5), a control device (60) for controlling, a conveying device (6) for conveying the bag film (5) and/or the bag body (16) along a conveying path (7), a welding device (8) with welding means (9, 10) for making a bottom seam (11) in the bag film and a cutting device (12) with a cutting means (13, 14) for separating a predetermined film length (15) of the bag film (5) to form the bag body (16) of an open-mouth bag (2). The control device (60) controls the conveying device (6) so as to cause a relative motion of the bag body (16) and the bag film (5) and a distance (37) between the bag body (16) and the bag film (5) is generated prior to making the bottom seam (11). The control device (60) controls the conveying device (6) and the welding means (9, 10) so that while welding the bottom seam (11) the welding means (9, 10) extend at least up to the bottom end (23) of the bag body (16).

APPARATUS AND METHOD FOR SECURING A ZIPPER CLOSURE TO POLYMERIC FILM

A method and apparatus for securing a zipper closure to polymeric film using minimal tension on the zipper closure includes providing first and second tension control loops, an eyemark detector, and a hole punch programmed to punch a hole in the zipper closure upon detection of the eyemark. The zipper closure and the film are supplied to a sealing station at the same speed, and the hole zipper closure is aligned with the eyemark on the film, to result in sealing the strip of zipper closure to the film resulting in minimal wrinkles to the resulting bag.
