Plastic Preopened Perforated Auto Bag Automatically Heat Sealed Auto Bag For Auto Bag Machine​

Description

From a structural point of view, the most notable feature of Pre-Opened Bags is that they have a pre-designed opening. This opening is completed during the bag manufacturing process, which is different from traditional sealed bags. The opening can take various forms, such as a neat cut at one end of the bag, or a special folding and bonding method to form an easy-to-open part. For example, it is common to have a heat-sealed line on the top of the bag, and a part of the heat-sealed line is cut as an opening; or there is a flap-type opening on the side of the bag made by a folding process, which allows users to directly access the inside of the bag.

Feature
 

Pre-opened bags can be made of a variety of materials. Common ones include plastics (such as polyethylene, polypropylene), paper materials, and composite materials (such as plastic-aluminum foil-plastic composite structures). Plastic bags usually have good flexibility, moisture resistance and transparency. For example, polyethylene bags are relatively cheap and highly transparent, and are often used to package daily necessities; polypropylene bags have higher strength and heat resistance, and are suitable for packaging items that require high-temperature treatment, such as some pasteurized foods. Paper pre-opened bags have good environmental protection and printing adaptability, and are often used for packaging with high requirements for product appearance, such as gift packaging, high-end brand product packaging, etc. Composite bags combine the advantages of multiple materials, such as good barrier properties (preventing oxygen, water vapor, etc. from entering), mechanical properties and fresh-keeping properties, and are often used to package medicines, high-end foods and other items that require high storage conditions.

Application:
 

Many cosmetic samples or travel packs are packaged in pre-opened bags. For example, for samples of creams and lotions, the pre-opened design is convenient for consumers to use. At the same time, the bag is mostly made of composite materials, such as a three-layer structure of plastic-aluminum foil-plastic. This structure can effectively prevent the active ingredients in the cosmetics from being oxidized and maintain the quality of the cosmetics. Exquisite brand logos and product descriptions can be printed on the surface of the bag to enhance the brand image.
