[0001] PRODUCTION OF ZIP-LOCK OR ZIPPER PACKAGING FROM BIOPOLYMERS

[0002] Technical Field

[0003] The present invention relates to the production of zip-lock or zipper packaging.

[0004] The invention particularly relates to a zip-lock or zipper packaging from compostable and / or biodegradable biopolymer, particularly made of 100% biopolymers and / or biopolymer combined with polyethylene polymers (at least 30%) and the production method thereof.

[0005] Description of State of the Art

[0006] Zip-lock or zipper packaging is used in the food, medical, textile and industrial sectors. Existing plastic packaging causes serious environmental pollution as it cannot be decomposed in nature for many years. Studies are being carried out on various developments in order to reduce the negative effects of plastic packaging on the environment and to minimise the amount of non-recyclable waste.

[0007] Application numbered TR 2007 / 06905 describes a zipper packaging suitable for automatic production, which is opened from the corner. An opening section consisting of a zipper made of synthetic resin is formed in one corner of a package consisting of a synthetic resin base material. The zipper made of synthetic resin is thermally bonded with a thermal sealing wing on only one side of each of the zipper female and male sections, wherein the zipper female and male sections are arranged in the inner direction of the zipper packaging and the thermal sealing wings are arranged in one direction of the corner of the opening section to obtain a thermally bonded structure for automatic production.

[0008] A technique for a different zipper packaging made of synthetic resin is described in this application. However, new packaging technical developments that minimise the negative effects on the environment are inevitable. As a result, new technical developments are required in zip-lock or zipper packaging used in various sectors.

[0009] The Aims of the Invention

[0010] Based on the state of the art, the aim of the invention is to develop a biopolymerbased zip-lock or zipper packaging that eliminates the negativities in existing structures.

[0011] Another aim of the invention is to develop a zip-lock or zipper packaging containing 100% biopolymer or at least 30% biopolymer combined with polyethylene polymers, and a production method for this packaging.

[0012] Another aim of the invention is to provide an environmentally friendly technical solution by means of the compostable and / or biodegradable properties of the developed packaging.

[0013] Another aim of the invention is to develop a compostable and / or biodegradable ziplock or zipper from biopolymers.

[0014] Another aim of the invention is for the produced zip-lock and / or zipper packaging to have biodegradable and / or compostable and / or recyclable properties.

[0015] In order to achieve the aforementioned aims, a zip-lock or zipper packaging has been developed from biopolymer that surpasses the state of the art with the technical advantages it provides.
