PRODUCT FEATURES
The side seal flat pouch is designed around the core principles of simplicity, efficiency, and cost-effectiveness. Featuring a fully flat structure without gussets, this pouch emphasizes lightweight versatility, making it the preferred choice for small-format, single-use packaging.

Materials typically include single-layer PE, BOPP, or thin composite films, all of which are food-grade, non-toxic, and odorless, fully compliant with safety standards. The lightweight, flexible, and compact design accommodates products ranging from 5g to several kilograms, significantly lowering storage and logistics costs while improving procurement efficiency.

FREQUENTLY ASKED QUESTIONS
1. Are three-side seal flat pouches firmly heat-sealed? Will they crack or leak under extrusion and long-distance transportation?
+
-
Our three-side seal pouches adopt high-temperature integrated edge sealing technology with consistent, sturdy seal lines. The sealed edges deliver excellent tensile and pressure resistance. They remain intact without edge cracking, delamination or air leakage during routine stacking, extrusion and logistics delivery. Stable sealing performance is maintained throughout storage and market circulation, effectively isolating moisture, dust and air to protect inner products from contamination.
2.Can these pouches support customized color printing and private logo branding? What printing processes are available?
+
-
Custom personalized printing is fully supported for three-side seal flat pouches. We provide eco-friendly gravure printing and high-definition digital printing services, covering brand logos, product ingredient lists, patterns, QR codes and customized text content. The printing ink is food-grade, non-toxic and odorless, featuring vivid color, strong adhesion and no fading, which effectively improves product grade and market competitiveness.
3. What is the MOQ for custom printed three-side seal flat pouches?
+
-
The minimum order quantity varies by printing process. Digital printing features flexible MOQ, ideal for small-batch trial orders and new product testing. Gravure printing requires customized printing cylinders and follows standard roll-based MOQ requirements. We offer flexible ordering solutions for emerging brands and personalized small-batch demands, balancing market trial needs and mass production cost efficiency.
4. Can the three-side seal pouches withstand high temperatures? Are they suitable for hot filling scenarios?
+
-
Conventional three-side seal pouches are suitable for normal-temperature filling and storage. For hot filling applications, we can upgrade the heat-resistant layer material structure. The optimized pouch can resist high temperature impact during hot filling, avoiding bag deformation, sealing damage or film softening. Please inform us of your specific hot filling temperature to match the most suitable heat-resistant packaging solution.
5.Are these three-side seal flat pouches suitable for vacuum packaging? Can they stay flat and neat after air extraction?
+-
This series of flat pouches is structurally optimized for vacuum packaging. Thanks to its flat profile and uniform material tension, the pouch can tightly fit product surfaces after air extraction, presenting a smooth, tidy finish without obvious wrinkles or warping. It thoroughly removes residual air inside the pouch to prevent product oxidation and mildew, perfectly fitting vacuum fresh-keeping packaging for food, electronic parts and hardware accessories.
