Description

Film bag structure

The present invention relates to a film bag body, more particularly a film bag body containing a toughened structure or a reinforcement layer, and is especially suitable for film bag bodies such as environmental protection bags and plastic bags.

In general life, users want the packaging bag to be cheap, easy to use, strong and tough, environmentally friendly and clean. After use, they also want the bag to be small and easy to store and organize. So at present, the film bag is still made of large Some plastics are used as bulk.

Most of the film bags use plastic as the raw material, and the most common bags on the market today are: polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), and oriented stretch polypropylene (OPP) films. , Generally referred to as plastic bags, because plastic bags have the advantages of waterproof, airtight, light, not easy to break, and low cost, easy processing, etc., so they are widely used in the packaging of items in daily life; even in many processing industries, Plastic bags are also often used as protection for certain processed objects.

However, people have also discovered that energy issues, air pollution, marine garbage, food safety and other current environmental issues are all related to plastics. Therefore, for environmental protection issues, some plants have begun to use environmentally friendly plastic materials such as polylactic acid (PLA) ) Is a thermoplastic aliphatic polyester; the lactic acid or lactide required for the production of polylactic acid (PLA) can be obtained by fermentation, dehydration, and purification of renewable resources. The resulting polylactic acid generally has good mechanical and processing properties. Gather After the lactic acid product is discarded, it can be quickly decomposed in various ways.

However, the cost of environmentally friendly materials is higher than that of plastics. Although plastic bags are cheaper, the surface of plastic bags is not tough enough. In order to strengthen the toughness, plastic bags must be thicker. This will increase the cost of production and is not environmentally friendly. So how to design a film bag body, its The bag body can enhance the toughness without increasing the thickness of the material, so whether the bag uses plastic or environmentally friendly materials, it can reduce the production cost and take into account the plastic reduction to achieve the goal of environmental protection. It is really an important technical issue worth discussing.

In view of the problem that the conventional bag body is not tough enough and easy to break, the present invention proposes a film bag structure, the purpose of which is to enhance the toughness of the bag body, so that the bag can be thin and practical, it includes a bag body, and the bag system uses A base layer is circled to form an accommodating space to form the film bag body for storing items, and at least one toughened structure is formed on the base layer, and the toughened structure is a geometric figure (eg, strip, mesh, Convex shape, etc.) to make the bag tough and not easy to break; or the surface of the base layer is provided with at least one reinforcement layer, which can be combined with the surface of the base layer by printing, coating, sticking, etc. To form this film bag that is durable and inexpensive to manufacture.
