Does PE agricultural film need to add aging masterbatch? If added, how much will the aging performance be improved?

Polyethylene (PE) is a thermoplastic resin polymerized from ethylene, and its appearance is a milky white colloid. Due to the characteristics of low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE) such as corrosion resistance, low hygroscopicity, soft texture, and excellent film-forming properties, most of the agricultural films used in daily life are low-density polyethylene and linear low-density polyethylene agricultural films. Agricultural films made of PE are produced by the extrusion blow molding method. They are light in weight, have a large unit coverage area, are easy to use, have good aging resistance and anti-fogging properties. According to their functions, they can be divided into PE aging-resistant films, PE aging-resistant drip-free films, PE aging-resistant dripping and anti-fogging films, PE mulch films, etc. 

At the same time, due to the poor aging resistance of PE, aging masterbatch must be added to better meet the needs of users.
