The present disclosure discloses an anti-counterfeit environment-friendly packaging material. The packaging material comprises an environment-friendly multilayer polymeric composite; and at least one iridescent non-metallic holographic stereogram in or on at least one layer of said environment-friendly multilayer polymeric composite. Also disclosed is a process for preparing an anti-counterfeit environment-friendly packaging material. The present disclosure further provides an anti-counterfeit reclosable package comprising the environment-friendly multilayer polymeric composite.

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 secondary packaging transport bag has a body (44) formed from a multilayer polyethylene film containing post-consumer resin. The body (44) defines a front panel (48), and a rear panel (52) located opposite the front panel (48). The front and rear panels (48, 52) define an open top edge (68) and are connected along opposite, left and right peripheral edges (56, 60) and are further connected along a bottom edge (64) to define an internal cavity (72) configured to receive packages in a distribution hub. The body (44) has a resealable closing means (76) proximate to the open top edge (68).

A zipper for a reclosable bag includes a first interlocking element, and a second interlocking element. The first interlocking element and the second interlocking element are configured to cooperate to selectively open and close the zipper. One or both of the first interlocking element and the second interlocking element are formed of at least 85% repulpable material.

A resealable storage bag features a dual-rib zipper profile in which two bulb-tipped male ribs on one wall lock into matching rounded grooves on the opposite wall, creating a robust airtight seal. An exterior slider with ergonomic pinch zones and a stepped, multi-slot channel guides the ribs into the grooves, allowing the seal to be achieved in a single pass even when the closure elements use softer resin blends. A hinged flap anchored to one wall carries at least part of the zipper profile and pivots between parallel and perpendicular positions. When the bag is stressed from below, the flap rotates to an orthogonal attitude that resists separation yet remains easy to open from above. A one-way valve enables vacuum evacuation for compact storage, while optimized divider lengths, ramp radii and slot clearances within the slider further enhance sealing reliability.

A safe guard zipper bag according to the present invention is composed of male and female coupling members. The male coupling member includes: a first support portion having a band shape extending in one direction; a protrusion portion protruding vertically from the first support portion; and a head portion made of first and second locking portions that extend in both directions from the tip of the protrusion portion. The female coupling member includes: a second support portion having a band shape extending in one direction; first and second side walls protruding in both directions from the second support portion; and first and second hook portions bent inward from the first and second side walls, respectively. The first locking portion of the male coupling member is located in the opening direction above the zipper, and the first locking portion protrudes toward the first side wall and is bent toward the first hook portion. The second locking portion of the male coupling member is located in the inward direction below the zipper, and the second locking portion protrudes toward the second side wall. An opening member in which the coupling force of the male and female coupling members is lost may be formed on one side of the zipper.

A lock includes: a base, an accommodating slot arranged on the base, and a movable plate fitted in the accommodating slot; wherein at least one deformation block, which is configured to be jammed into the accommodating slot, is set on the movable plate; at least one restriction block, which is configured to be locked in the accommodating slot, is set on the movable plate; a lever plate is provided on the base, which is configured to release the deformation block and thus releasing the movable plate; the lever plate comprises a working part, a connecting part and a pressing part, wherein the connecting part is pivotally coupled to the base. The accommodating slot on an external side of the base is used to lock the movable plate, and the lock can be opened only by pressing the pressing part.
