The center seal pouch—also known as a back seal pouch or pillow pouch—is one of the most widely used formats in the laminated packaging industry due to its high versatility, ease of processing, and production cost optimization. Featuring a simple design with a single longitudinal seal down the center of the back panel, these pouches offer high packaging efficiency while ensuring excellent airtightness, durability, and aesthetic appeal.
At Long Vu Packaging, we do more than just manufacture high-quality center seal pouches; we provide expert consultation to determine the most suitable film structure for your specific product and industry. With over 10 years of experience, we understand the nuances that help businesses minimize costs while achieving peak packaging performance.
Center seal pouches can be engineered from various multi-layer structures depending on preservation requirements and technical specifications. We offer a wide range of options tailored to specific product groups:
| Laminated Structure | Technical Characteristics | Suitable Industries |
| OPP/CPP | High clarity, cost-effective, moisture resistant | Confectionery, FMCG |
| PET/PE | Durable, flexible, superior printability | Dried foods, cosmetics, promotional items |
| PET/AL/PE | Absolute light and odor barrier | Pharmaceuticals, premium cosmetics |
| PET/METPET/PE | UV barrier, enhanced aesthetic metallic finish | Snacks, coffee, tea |
| PA/PE | High puncture resistance, excellent vacuum properties | Sausages, frozen foods |
These structures are designed to protect products from moisture, light, oxygen, and other environmental factors.
Center seal pouches are ideal for mass production and are highly compatible with high-speed Vertical Form-Fill-Seal (VFFS) machinery.

To ensure packaging efficiency and brand value, businesses should consider the following during the design phase:
Safe Zones: Avoid placing critical design elements too close to the seal areas to prevent distortion or loss of detail.
Back Seal Clearance: Strategically plan the back panel layout so the center seal does not obscure important product information or barcodes.
Message Optimization: Prioritize a high-impact front panel design while reserving the back for detailed technical data.
Barrier Selection: Choose materials based on the product’s sensitivity; products prone to oxidation require AL (Foil) or MPET (Metalized) layers.
Film Gauge (Thickness): Calibrate the film thickness based on product weight, filling speed, and required shelf life.
Structural Consultation: Matching the right materials to the industry.
Brand-Centric Design: Creating layouts that align with brand identity.
High-Definition Printing: Utilizing premium inks for vibrant, stable colors.
Dry/Solvent-less Lamination: Using food-safe, non-toxic adhesives.
Curing/Heat Aging: Ensuring a permanent, high-strength bond between layers.
High-Speed Conversion: Automated pouch forming and precision cutting.
