[0002] Composite film bags are packaging bags made of two or more materials, usually made by bonding and heat-sealing different materials together. This type of packaging bag has multiple functions, such as protecting food, electronic products, chemical products, medicine, tea, precision instruments and cutting-edge defense products. The materials of composite film bags include but are not limited to OPP, PE, POF, PPE, PP, etc., among which BOPP / LLDPE two-layer composite is a common material combination. The process of composite film bags is divided into side-sealed bags and bottom-sealed bags. Its structure generally includes a base layer, a functional layer and a heat-sealing layer. The base layer mainly plays the role of aesthetics, printing, and moisture resistance, the functional layer mainly plays the role of barrier and light protection, and the heat-sealing layer is in direct contact with the packaged items and has functions such as adaptability, permeability resistance, and heat sealing.

[0003] Ultraviolet rays are part of solar radiation with a shorter wavelength and higher energy, so they may damage certain items or materials. Conventional composite film bags have a thin structure, so exposure to ultraviolet rays can cause organic materials to age, fade, and turn yellow, or damage some electronic equipment.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a transparent high-barrier composite film bag is proposed. Utility Model Content
