A sealing zipper according to an embodiment of the present invention includes a first chain portion, a second chain portion coupled to the first chain portion, a chain fixing portion coupled to one end portion of the first chain portion and one end portion of the second chain portion, and a watertight portion positioned between the first chain portion and the second chain portion and disposed to be partially inserted into the chain fixing portion.

This disclosure relates generally to production of clean textiles and, more particularly, to cleaning articles, such as wipers, mops, and swabs, made of a recycled or “upcycled” material for use in a cleanroom environment, and methods for producing such cleaning articles. Such cleaning articles may comprise at least one layer of fabric. The fabric may be formed from at least 50% recycled yarn, and the remainder of the wiper, if any, may be formed from virgin yarn. The recycled yarn may be recycled polyester yarn. The edges of the at least one layer of fabric may be sealed or cut.

A reusable container having a pouch portion and a slide lock portion. The pouch portion can be a rectangular, flat pouch. The slide lock system can seal a top portion of the pouches sealing mechanism. The sealing mechanism can allow a user to store liquids conveniently therein without risk of spilling while also providing a reusable easy to clean container.

A biodegradable (repulpable, compostable and/or water soluble) zipper is provided for attachment to a biodegradable flexible package. The biodegradable zipper is formed using a water-soluble polymer that can be combined with a repulpable and/or compostable material, such as a plant-based cellulose material. The biodegradable zipper enables the biodegradable package to be opened and closed by the consumer, so that the consumer has the option to determine, change or manipulate the contents of the biodegradable flexible package.

A repulpable zipper is provided for attachment to a repulpable flexible package. The repulpable zipper is formed using a water-soluble polymer combined with a repulpable material, such as a plant-based cellulose material. The repulpable zipper enables the repulpable package to be opened and closed by the consumer, so that the consumer has the option to determine, change or manipulate the contents of the repulpable flexible package.

The present disclosure is appropriate for the technical field of packaging bag materials, and provides a full biodegradable high-barrier multi-layer composite material and a preparation method thereof as well as a packaging bag. The full biodegradable high-barrier multi-layer composite material comprises the following components: polylactic acid, terephthalic acid-adipic acid-butanediol copolyester, polyvinyl alcohol, polyurethane glue and starch carrageenan. Embodiments of the present disclosure provide the full biodegradable high-barrier multi-layer composite material which is obtained by using the terephthalic acid-adipic acid-butanediol copolyester as a degradable layer, using polyvinyl alcohol as a barrier layer and by composing the degradable layer with the barrier layer via polyurethane glue and starch carrageenan. Through the present disclosure, the problems, such as high oxygen permeation rate, poor barrier property and poor preservation degree, in the existing degraded film can be solved.

A plastic slider zipper is disclosed which includes a pair of plastic zipper strips with ends melted together to form an end piece with a predetermined thickness, a slider slidably engaging the pair of plastic zipper strips with two side walls and a plow, a first gap between the two side walls near a first end of the slider being small enough to squeeze the zipper strips into an interlocking position, the plow located between the two side walls being able to separate the interlocked zipper strips, a top of the slider having an opening near a second end of the slider, the second end being opposite to the first end, and a fork-like part removably inserted in the opening, the fork-like part having two columns with a space therebetween approximately matching the predetermined thickness for the two columns to straddle the end piece.

A package includes a first layer, the first layer adapted to receive a consumer good, a second layer, the second layer including a humidity control pack, and a third layer laminated in-between the first layer and the second layer.

A child-resistant reclosable bag includes a container configured to retain one or more items within a product portion. A zipper is coupled to the container. The zipper is above the product portion. The zipper includes one or more primary seals, and one or more secondary seals at one or more defined locations. The one or more secondary seals at the one or more defined locations identify opening areas on the product portion. The opening areas are configured to be grasped and pulled apart to open the zipper.

A repulpable zipper is provided for attachment to a repulpable flexible package. The repulpable zipper is formed using a water-soluble polymer combined with a repulpable material, such as a plant-based cellulose material. The repulpable zipper enables the repulpable package to be opened and closed by the consumer, so that the consumer has the option to determine, change or manipulate the contents of the repulpable flexible package.
