25g Facial Mask Three Side Seal Sachet
Custom-manufactured flexible packaging for clay masks, mud masks and other viscous skincare pastes. It adopts BOPET/AL/BOPET/IPE multi-layer high-barrier composite laminate. The intermediate aluminium foil layer forms a reliable barrier against light, oxygen and moisture, effectively suppressing oxidation and degradation of active ingredients inside, preserving the activity, flavour and efficacy of mask essence throughout the shelf cycle. Accurate three-side thermal sealing provides consistent sealing strength and outstanding leakage resistance. The flat pouch profile is well adapted to high-speed automatic filling equipment, supporting continuous and stable packaging operation for skincare mask products.
Product features

Multi-layer High-barrier Laminate Material
Constructed with BOPET/AL/BOPET/IPE multi-layer composite structure. The embedded aluminium foil interlayer creates a robust barrier against light, oxygen and water vapour. It effectively suppresses oxidative deterioration, blocks moisture and airborne contaminants, and slows the deactivation of skincare actives. The well-bonded lamination avoids delamination under normal storage, stably preserving the freshness, texture and efficacy of mask essence throughout the whole shelf life.
Elegant Flat Three-side-seal Display Effect
Slim flat three-side-seal silhouette with smooth, evenly formed heat-seal edges. It supports flexible display solutions including neat stacking, tray arrangement and hanging presentation with optional hang holes. The streamlined pouch shape does not compete with printed graphics, fully showcasing custom artwork and delivering a minimalist, premium skincare aesthetic to capture consumer attention amid crowded retail shelves.


Versatile Customization Service
Full-range customisation is available, covering pouch dimensions, hang hole types, surface finishes (glossy, matte, soft-touch), CMYK colour printing and special finishing such as hot stamping, embossing and spot UV. Brand logos, colour palettes and graphic layouts can be precisely tailored to match your brand identity, market positioning and packaging design requirements. Sample service is supported for effect verification before mass production.
Compact & Convenient for Storage & Shipment
Lightweight flexible flat pouch design. Empty sachets can be stacked closely together without wasting warehouse space. The composite film boasts good flexibility and puncture resistance, which can withstand squeezing, rubbing and impact during long-distance logistics, lowering the risk of rupture and liquid leakage. Its low weight increases container loading capacity and effectively reduces overall freight cost.
