Product Range and Specialties of Zhanjiang Fengqi Plastic Product Co., Ltd.

The catalogue lists 30 distinct envelope and film wallet types, ranging from plain packing list envelopes to pressure‑sensitive and waterproof variants. Materials mentioned are polyethylene (PE) and polypropylene (PP), both common in flexible packaging for their moisture resistance and durability. In the broader industry, PE envelopes are typically produced in low‑density (LDPE) or linear low‑density (LLDPE) grades with thicknesses from 20 µm to 80 µm, while PP films often use B‑type or C‑type grades with similar thickness ranges. Self‑adhesive envelopes usually employ pressure‑sensitive acrylic or rubber‑based adhesives that retain tack over a wide temperature range, and waterproof printed envelopes are commonly coated with a thin polyester or polypropylene laminate to protect printed information.
