Product Overview
Flat Bottom Pouch, also known as Eight-Side Seal Pouch or Box Pouch, is a high-end rigid flexible packaging structure combining double side gussets and a fully flat sealed bottom. Manufactured with multi-layer food-grade composite film materials, supplied in industrial composite film rolls and finished flat bottom pouches. Featuring eight-edge full sealing and box-shaped three-dimensional structure, the pouch stands ultra-stably at any filling level. It is widely used for high-end coffee beans, loose tea, nuts, dried fruits, grain products, protein powder, pet food, luxury daily chemicals and retail high-grade product packaging, becoming the mainstream premium packaging solution for supermarket shelf display.
Composite structure options:
PET/PE, PET/AL/PE, NY/PE, NY/AL/PE, recyclable mono-PE, matte/glossy/soft-touch composite film.Available thickness:

Key Features & Benefits
Eight-Side Seal & Rigid Box-Shaped Structure
Unique eight-edge full sealing design with fully flat expanded bottom. Forms a standard square box shape after filling, no tilting or collapsing. Provides firmer three-dimensional support than stand-up pouches and side gusset pouches for premium shelf performance.
Maximum Capacity & Space Utilization
Vertical side gussets plus flat bottom expand to the maximum internal space. Larger loading capacity than ordinary pouches with the same outer size, saving packaging and transportation costs effectively.
360° Full-Surface Premium Brand Display
Five visible display panels (front, back, two sides, bottom) with zero printing dead angles. Supports all-around high-definition branding and pattern presentation, ideal for high-end product positioning and retail marketing.
Ultra-High Barrier & Fresh-Keeping Performance
Multi-layer dense composite structure strongly isolates oxygen, moisture, light and odor. Achieves long-term aroma locking, oxidation resistance and moisture proof, perfectly suitable for high-value sensitive products such as specialty coffee and premium tea.
Strong Structural Toughness & Pressure Resistance
Eight-edge balanced sealing force disperses external pressure evenly. Resists extrusion, puncture and cracking during long-distance transportation and stacking, with extremely low damage rate.

FAQ & Quality Solutions
Unstable standing and deformed box shape
Optimize synchronous forming technology for double gussets and flat bottom, calibrate multi-station mould tolerance to ensure symmetrical expansion and standard box shaping.
Seam edge cracking or local leakage
Adjust segmented heat-sealing parameters for eight edges, optimize corner transition pressure to avoid stress concentration and ensure uniform sealing firmness for all edges.
Insufficient fresh-keeping and aroma loss
Upgrade ultra-high barrier aluminum foil composite structure, increase film thickness appropriately; match high-quality one-way degassing valve for coffee packaging to exhaust residual oxygen and lock aroma.
Print pattern stretching and distortion at gusset and bottom joints
Adopt professional pre-compensation printing technology, precisely control folding and forming tolerance to ensure complete and undistorted pattern presentation after three-dimensional shaping.
Printed ink scratches, peels off or fades easily
Apply high-adhesion packaging ink and surface varnishlamination protection. Complete full ink curing process, and conduct friction and aging tests to enhance scratch resistance and color stability.
Zipper jamming, loosening or poor sealing
Adopt high-precision food-grade zipper strips, optimize hot-press fitting temperature and pressure, conduct repeated opening-closing and sealing aging tests before mass production.
Pouch film wrinkles and deforms after filling and stacking
Precision tension control during film rolling and pouch forming process. Optimize heat-sealing and shaping process to avoid uneven stress, ensuring smooth and flat pouch body after filling.
Residual peculiar odor on finished pouches
Select low-odor food-grade raw materials and environmental ink, complete full curing and ventilation process to eliminate residual smell.
Uneven film thickness and batch difference
Equip with online automatic thickness monitoring system during film production, stabilize calendering and composite parameters to ensure uniform thickness and consistent quality across batches.

Shipping & Logistics Recommendations
Composite film rolls wrapped with waterproof film and fixed with edge guards on pallets to prevent moisture absorption and extrusion damage. Finished flat bottom pouches packed flat with sealed inner bags + reinforced corrugated master cartons, palletized for long-distance sea freight. Store in dry, ventilated and constant-temperature warehouse; avoid high temperature, humidity and direct sunlight to prevent film aging and barrier attenuation. Stack height ≤1.2m to prevent carton deformation, edge sealing crease and box shape damage. Complete packaging safety test reports and compliance certificates provided for customs clearance. 24-hour after-sales support for packaging matching and quality consultation.
