Eco-Friendly Wet-pressed Molded Pulp Test Tube Holder

This product is manufactured using the wet-pressed pulp molding process, made from 100% natural plant fibers (bagasse, bamboo, wood pulp) through pulping, vacuum forming, and hot-press shaping. Specifically designed as eco-friendly packaging and transport fixation for various laboratory tubes — including blood collection tubes, centrifuge tubes, PCR tubes, cryovials, and more. The molded pulp test tube holder offers excellent cushioning protection, full biodegradability, and flexible customization capabilities. It is the ideal green packaging upgrade for medical diagnostics, biopharmaceuticals, and IVD industries seeking sustainable alternatives to single-use plastic packaging.

product details

The Paper Pulp Molded Test Tube Holder is Esen's flagship eco-friendly packaging product developed through wet-pressed pulp molding technology. Made from natural plant fibers and produced via a three-stage process — pulping, vacuum forming, and hot-press setting — the product range covers 6-well to 96-well configurations, accommodating tubes from 2mL to 50mL. This tray provides a full-chain green packaging solution for medical labs, biopharmaceutical facilities, and research institutions.

1.Eco-Friendly & Biodegradable

100% natural plant fibers, zero plastic content. Naturally degrades within 60-90 days with no microplastic pollution. Complies with the EU Single-Use Plastics (SUP) Directive and global ESG regulations.

2.Multi-Dimensional Cushioning

The wet-pressed process enables precise wall thickness control within 0.8-1.2mm. Nubs, grid patterns, and reinforcing ribs are strategically designed to absorb impact forces and vibrations during transport, significantly reducing tube breakage rates.

3.Anti-Shift Fixation

Each cavity features a contoured groove that conforms tightly to the tube shape, preventing shaking, collision, or detachment during transit. Particularly suitable for cold chain logistics and long-distance cross-border shipping.

4.Superior Stacking Strength

After hot-press setting, the product achieves excellent rigidity and hardness, supporting multi-layer stacking. This significantly saves warehouse space and reduces per-unit logistics costs.

5.Flexible Customization

Supports custom well counts, tube diameters, surface coating (moisture-proof/anti-static/dust-proof), silk-screen Logo printing, QR code traceability, and more. Mold development cycle is only 15-20 days with flexible MOQ.

6.Hygiene & Safety

Natural plant fibers undergo high-temperature hot-press sterilization. No plasticizers, BPA, or other hazardous substances leach out. Meets food-grade and medical-grade safety standards, compliant with ROHS, REACH, and FDA regulations.
