Description
本創作涉及包裝材料及使用包裝材料製成的包裝袋,尤指一種用於物流的包裝材料及主要以其製成的物流包裝袋。This creation involves packaging materials and packaging bags made of packaging materials, especially a packaging material used for logistics and logistics packaging bags mainly made of them.
在網路購物發達的時代,愈來愈多商品需要透過物流的方式從店家(即寄件者)傳輸到消費者(即收件者)手中。因此,如何有效確保商品在整趟運輸過程中都保持完整,成為贏得寄件者及收件者青睞的關鍵要素。In the era of developed online shopping, more and more commodities need to be transported from the store (ie the sender) to the consumer (ie the recipient) by means of logistics. Therefore, how to effectively ensure that the goods remain intact throughout the entire transportation process has become a key factor in winning the favor of senders and recipients.
以往,因發泡聚乙烯(expanded polyethylene foam,EPE)具有良好的回復性,即便受到碰撞、被壓縮也能回復彈性,因此包裝緩衝材大都由單層EPE所構成。但為了印製商標等需求,故有時需把不易印刷的EPE製成內襯與紙製外層一起組成信封或包裝袋。若EPE內襯和紙製外層未使用膠材貼合,則會有使用時牢固性不佳的問題;反之,若將EPE內襯和紙製外層以膠材黏合,雖可克服上述牢固性不佳的問題,但在使用後會有不易將EPE內襯和紙製外層分開,而存在不利於回收的問題。In the past, because expanded polyethylene foam (EPE) has good recovery properties, even if it is impacted and compressed, it can recover elasticity, so the packaging buffer materials are mostly composed of a single layer of EPE. However, in order to print trademarks and other needs, sometimes it is necessary to make the inner lining of EPE, which is not easy to print, and the outer layer of paper to form envelopes or packaging bags. If the EPE inner lining and the paper outer layer are not glued together, there will be a problem of poor firmness during use; on the contrary, if the EPE inner lining and the paper outer layer are bonded with glue, although the above-mentioned poor firmness can be overcome. However, it is difficult to separate the EPE inner liner and the paper outer layer after use, which is not conducive to recycling.
申請人已於早年開始進行一些關於包裝緩衝材的研發,如中華民國新型專利第M495946號,其提供一種具高強度性的包裝緩衝材,所述包裝緩衝材主要包含一編織層以及一設置於該編織層內側的緩衝層,該編織層可由高密度聚乙烯(high density polyethylene,HDPE)材質的帶體編織而成,而該緩衝層可由EPE所形成;由於該編織層係由帶體編織而成,因此該編織層外表面會呈現明顯不平整、有起伏的表面結構,若作為物流包裝袋的包裝材料則會存在不利於後續印刷的問題。雖然M495946提出可於該編織層外側面再形成一平滑的修飾層,但如此一來將造成包裝緩衝材的生產成本較高。再者,若該修飾層太薄,該編織層的編織圖案仍會清楚地顯現於修飾層而減損美觀程度,而無法滿足日益重視外觀質感的要求;反之,若該修飾層太厚,當該修飾層與該編織層的接著強度不夠時,會容易發生剝離現象,且無法滿足對於用於物流的包裝材料的輕量化需求。The applicant has started some research and development on packaging buffer materials in the early years, such as the Republic of China Patent No. M495946, which provides a high-strength packaging buffer material, the packaging buffer material mainly includes a woven layer and a The buffer layer inside the braided layer can be woven from a belt body made of high density polyethylene (HDPE), and the buffer layer can be formed of EPE; because the braided layer is woven from the belt body Therefore, the outer surface of the braided layer will have a significantly uneven and undulating surface structure, and if it is used as a packaging material for a logistics packaging bag, there will be problems that are not conducive to subsequent printing. Although M495946 proposes to form a smooth decorative layer on the outer side of the braided layer, this will result in a higher production cost of the packaging buffer material. Furthermore, if the decoration layer is too thin, the weave pattern of the weave layer will still be clearly visible on the decoration layer, which will detract from the aesthetics, and cannot meet the requirements of increasing emphasis on appearance and texture; on the contrary, if the decoration layer is too thick, the When the bonding strength between the decorative layer and the braided layer is insufficient, peeling may easily occur, and the lightweight requirements for packaging materials used for logistics cannot be met.
有鑑於此,本創作之目的在於提供一種具有良好減震性,且易於回收的適合用於物流的包裝材料。In view of this, the purpose of this creation is to provide a packaging material suitable for logistics that has good shock absorption and is easy to recycle.
