Embodiment

[0020] For the opening accessories, in this paper, it is mainly various base materials and glues.

[0021] Requirements for the workshop: Purify the workshop to control the amount of dust in the air. The workshop is transformed into double-glazed windows, double-layer doors, equipped with air conditioners, and insect repellent treatment is carried out within 500 meters around.

[0022] The opening auxiliary material adding process of the packaging bag comprises the following steps:

[0023] 1. Base material unwinding, using ordinary unwinding device, the function is to load the material, transport the base material, and provide it to the follow-up equipment, and the unwinding speed can be properly controlled; three base materials are provided, which are respectively used as the inner layer base material: vinyl Modified copolymer polypropylene, middle layer substrate: aluminum foil; outer layer substrate: nylon or polyester resin. The three-layer substrate is stacked sequentia...

Abstract

The invention discloses an opening auxiliary material adding process for a packaging bag, and belongs to the technical field of packaging bags. The problems about production efficiency and productionquality are solved. According to the technical scheme, a new processing technology is adopted to transform processing of the packaging bag, operation is carried out step by step and controlled from multiple directions, and the effects of efficient production and improvement of the production quality are achieved.

Description

technical field [0001] The invention relates to the field of packaging bags, in particular to a process for adding auxiliary materials for opening of packaging bags. Background technique [0002] Polyethylene is currently the most important general-purpose plastic in the world, and it is also the polymer material with the largest output and the widest application among synthetic resins. It is formed by addition polymerization of ethylene (CH2=CH2). In industry, polyethylene also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene can be processed by general thermoplastic molding methods. It is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -70 to -100 ° C), good chemical stability, and can withstand most acids. Alkali erosion (not resistant to oxidizing acids), insoluble in general solvents at room temperature, low water absorption, but because it is a linear molecule, it ca...
