100% Virgin PLA and PETG Raw Materials: No Recycled Material Added
The video shows white raw-material pellets in open containers, stainless-steel feed hoppers, and the factory's material-handling area. WJ uses virgin PLA, PETG, and other specified plastic raw materials for FDM filament production and does not add recycled material.
What this raw-material handling video actually shows
The camera moves through a factory material area with multiple stainless-steel hoppers, blue support frames, white containers, and visible white raw-material pellets. Near the end, the pellets are shown by hand at close range. These are direct observations from the footage.
A short video cannot independently identify the polymer grade, supplier, batch number, moisture level, or final filament performance. Those points should be connected to the purchase specification, raw- material identification, approved sample, batch record, and inspection terms for each OEM order.
How OEM buyers can verify a virgin-material requirement
- Write "virgin PLA or PETG raw material, no recycled material" directly into the approved product specification.
- Confirm the required polymer type, grade, supplier reference, color, and additive requirements.
- Ask how incoming material and production batches are identified and recorded for repeat orders.
- Keep the approved filament sample, packaging details, and inspection terms linked to the same order.
- Request supplier confirmation when your market or customer requires additional raw-material documents.
Why avoiding recycled material matters for OEM filament programs
The source and grade of PLA, PETG, or another specified plastic raw material are inputs behind color matching, processing behavior, and repeat-order consistency. Using a defined virgin-material policy gives distributors and private-label brands a clearer purchasing baseline. The policy still needs to be paired with the correct material grade, production controls, approved sample, and inspection requirements for the specific filament being ordered.
Factory video summary for virgin-material filament buyers
This WJ factory video shows white raw-material pellets, material containers, and feed hoppers inside an OEM 3D printer filament factory. WJ states that it uses virgin PLA, PETG, and other specified plastic raw materials and does not add recycled material. The page helps buyers prepare questions about material grade, material source, batch identification, samples, inspection terms, and repeat private-label orders.
