Guangdong Defeng Materials, established in 2019 in Lilin Town, Huizhou, is a professional manufacturer of rigid plastic packaging materials & finished packaging products.
We produce PET, PETG,RPET, PET/PE laminated, PP sheets, blister packs,serving food, medical, electronics, cosmetic and daily‑chemical industries, with global well‑known brand clients.
Our facility spans 11,000㎡, housing 5 sheet lines, 5 blister lines, 7 injection‑molding lines and dust‑free workshops. Annual capacity: 9,500 tons for sheets & blister packaging. We employ over 100 staff including 11 R&D engineers and professional QA team with complete testing equipment.
We hold ISO9001, ISO13485, ISO22000 and BRC certifications; our products comply with FDA, REACH and RoHS standards.
We deliver customized one‑stop packaging solutions. Lead time: 7 days for thermoforming sheets, 15 working days for blister trays.
Thermoforming is a process in which extruded plastic sheets are heated and softened, then formed against molds using vacuum or air pressure. After cooling and solidification, they are made into three-dimensional packaging products or containers. This process works together with sheet extrusion to achieve integrated “sheet-to-product” production.
Sheet Feeding & Heating Plastic sheets or rolls are fed into the heating oven and uniformly heated to the appropriate softening temperature to ensure good flexibility and formability.
Forming The softened sheet is transferred to the mold and formed by vacuum or air pressure, closely conforming to the mold cavity to create the required three-dimensional shape, such as trays, clamshells, and containers.
Cooling & Solidification Air cooling or mold cooling is used to solidify the formed products, ensuring dimensional stability and surface quality.
Demolding & Trimming After demolding, the products undergo cutting, edge trimming, and punching to achieve the required dimensions, followed by counting, stacking, and packaging.

01 — Sheet Extrusion Line
Sheet extrusion is a continuous manufacturing process in which polymer materials are heated, melted, mixed, co-extruded, calendered, and cooled to produce high-quality plastic sheets. A complete sheet extrusion line mainly consists of three key sections: extruders, die, and downstream equipment.
Extruder Raw materials are fed into the heated barrel, where they are heated, melted, and thoroughly mixed by the screw. The molten material is then filtered, pressure-stabilized, and precisely metered before entering the co-extrusion die.
For our typical 3-layer structure (skin / core / skin), three extruders process the materials separately. The three molten layers are then combined through a co-extrusion feedblock to form a single sheet.
Die The die evenly distributes and shapes the molten plastic into a flat sheet, while precisely controlling the sheet width, thickness, and melt flow to achieve consistent product quality.
Downstream Equipment The downstream equipment continuously draws the sheet from the die and provides precise control over sheet thickness and dimensions. Depending on the product requirements, the required surface treatment can be applied during the processing stage. After sufficient cooling, the sheet is trimmed, cut to the required size, or wound into rolls to produce the finished material according to customer specifications.
Core Advantages of Our Plastic Sheets
♻️Recyclable: Recyclable and environmentally friendly, supporting sustainable packaging solutions.
⚡ Anti-Static: Optional anti-static treatment for packaging electronic and precision components.
