Custom Wet Pressed Pulp Lipstick Refill Clamshell Package

Esen's wet-pressed pulp molded lipstick refill clamshell is the industry's first all-pulp, zero-plastic clamshell packaging designed specifically for lipstick refills. Molded from sugarcane bagasse , bamboo and wood fiber, this innovative clamshell structure replaces traditional plastic snap-case refill packaging entirely. The hinged one-piece design opens to securely cradle a lipstick bullet, then snaps shut for protection during transit and retail display. Fully biodegradable, EU PPWR compliant, and compatible with standard lipstick refill programs, this packaging enables beauty brands to eliminate plastic from their refill systems without compromising on protection or user experience.

product details

1.Clamshell Structure — One-Piece Hinged Design

Unlike conventional pulp trays that are open-top, our clamshell features an integrated hinge and snap-latch mechanism formed entirely from molded pulp fiber. The base securely holds the lipstick bullet in a precision-contoured cavity, while the lid closes and stays closed during shipping. No adhesive, no plastic clips, no secondary components.

The hinge is engineered to withstand repeated open-close cycles, allowing consumers to easily access the lipstick while keeping the refill securely enclosed before first use.

2.Precision Bullet Cavity

Each clamshell is molded from the lipstick's 3D data, creating a cavity that precisely matches the bullet's contours. The lipstick sits snugly without rattling, and the lid's interior surface gently contacts the top of the bullet to prevent vertical movement. Tolerance is controlled within ±0.3mm.

3.Snap-Shut Protection — Fiber Latch

The clamshell incorporates an integrated fiber latch at the closure edge. When pressed shut, the latch engages to hold the lid firmly in place. This provides reliable closure security during handling, transit, and retail shelf display, eliminating the need for plastic shrink bands or adhesive seals.

4.Thin-Wall Precision Molding

Wall thickness is maintained at 0.8–1.2mm, creating a slim, lightweight package that fits within standard lipstick carton dimensions. Despite the thin walls, the wet-pressed fiber structure provides sufficient rigidity to protect the lipstick bullet from compression and impact.

5. Refill-Ready — Compatible with Standard Refill Systems

•100% plant-based fibers: sugarcane bagasse + bamboo pulp+wood pulp
•Fully biodegradable: 6-12 months in home compost, 45-60 days industrial composting
•Zero plastic, zero glue, zero waste in production
•Helps brands meet EU PPWR, UK Plastic Tax, and ESG commitments

6. Natural Aesthetics — A Statement of Sustainability

The clamshell's natural paper fiber texture and warm earth-tone color communicate environmental responsibility at a glance. Brands can emboss logos directly into the pulp during molding, eliminating the need for labels or secondary printing. The visual and tactile experience tells consumers: "This is the future of packaging."
