Base fabric tapes: Primarily composed of polypropylene (PP)-the mainstream choice in the domestic market for balancing strength and rigidity-though polyethylene (PE) is used in a minority of cases requiring low-temperature resistance or specialized properties.
Liner/composite layer (for moisture protection): Typically made of low-density polyethylene (LDPE) or ethylene-vinyl acetate (EVA) co-extruded film; serves as a moisture barrier to prevent the feed from becoming damp or moldy.
Additives: Ingredients such as calcium masterbatch (to enhance rigidity), color masterbatch (for coloration), UV stabilizers, and antioxidants are incorporated during production to improve weather resistance and service life.
