Description

Technical Field

[0001] This utility model relates to the field of bio-based polylactic acid packaging equipment technology, and in particular to a bio-based polylactic acid shopping bag with a wear-resistant inner film. Background Technology

[0002] Bio-based polylactic acid (PLA) shopping bags are an environmentally friendly type of shopping bag. Their main material, PLA, comes from renewable biological resources such as corn starch and sugarcane. These shopping bags are biodegradable, have good physical properties, and are biocompatible, and therefore are receiving increasing attention under the modern concept of environmental protection.

[0003] Bio-based polylactic acid shopping bags can be decomposed into carbon dioxide and water by microorganisms under certain conditions, returning to the natural cycle and not causing long-term environmental pollution. Because the raw materials come from renewable plant resources, it reduces dependence on fossil fuels, lowers carbon emissions, has good transparency, and is aesthetically pleasing. It is similar to traditional plastic bags but more environmentally friendly.

[0004] However, the applicant has found that the prior art has at least the following problems:

[0005] Most existing bio-based polylactic acid shopping bags have thickened bottoms and thin sides, resulting in low abrasion resistance. Furthermore, the edges of the bags are prone to wear and tear, leading to rips and rendering the bags unusable. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a bio-based polylactic acid shopping bag with a wear-resistant inner membrane to solve the problems mentioned in the background art.

[0007] Based on the above objectives, this utility model provides a bio-based polylactic acid shopping bag with a wear-resistant inner membrane, comprising a shopping bag body, an inner membrane layer, and a thickened edge. The inner membrane layer is fixedly connected to the inside of the shopping bag body, and the thickened edge is fixedly connected to the top of the shopping bag body and the inner membrane layer. The inner membrane layer is made of reinforcing fiber material. The bag also includes a long handle, a locking mechanism, and a slot. The long handle is fixedly connected to the upper outer side of the shopping bag body, the locking mechanism is located at one end of the long handle, and the slot is located at the other end of the long handle.

[0008] Optionally, it also includes a removable abrasion-resistant layer one and a removable abrasion-resistant layer two. The removable abrasion-resistant layer one is disposed on one side inside the inner membrane layer, and the removable abrasion-resistant layer two is disposed on the other side inside the inner membrane layer. Both the removable abrasion-resistant layer one and the removable abrasion-resistant layer two are made of cellulose pulp material.

[0009] Optionally, the locking mechanism includes a silicone insert, a female buckle, and a male buckle. The silicone insert is movably connected to the long handle of the shopping bag and is adapted to the insertion port. The female buckle is fixedly connected to the upper end of one side of the silicone insert, and the male buckle is fixedly connected to the lower end of the other side of the silicone insert. A female hook and loop fastener is also included. The female hook and loop fastener is fixedly connected to the other side of the silicone insert and located below the female buckle. The male hook and loop fastener is fixedly connected to the other end of the silicone insert and located above the male buckle.

[0010] Optionally, it also includes short handles, with two sets of short handles symmetrically arranged at both ends of the top of the thickened edge.

[0011] Optionally, the shopping bag has two sets of long handles and slots, with the two sets of long handles symmetrically arranged on both sides of the shopping bag body.

[0012] Optionally, there are two sets of both the first and second removable anti-wear layers. The two sets of the first removable anti-wear layers are symmetrically arranged on both sides of the inner film layer, and the two sets of the second removable anti-wear layers are symmetrically arranged on the other two sides of the inner film layer.

[0013] The beneficial effects of this utility model are as follows: The inner membrane layer inside the shopping bag effectively improves its abrasion resistance and tear strength, forming a multi-layered composite structure that further enhances the overall durability of the shopping bag. The thickened edge at the top of the shopping bag body and inner membrane layer reinforces the edges, preventing edge damage caused by pressure or pulling from heavy objects. Two sets of long handles facilitate hand carrying; they can be slung over the shoulder for easier carrying of a full bag. A locking mechanism secures the two long handles to the bottom of the shopping bag body, enhancing its support. Silicone inserts are inserted into the openings of the two long handles, bending and folding them to engage the female and male snaps, and to adhere the female and male sides of the Velcro, thus securing the two long handles. The removable abrasion-resistant layer one and two further enhance the abrasion resistance of the shopping bag body, while their removable design allows users to easily replace or clean them as needed.
