Our Skills
As a professional lunch bag manufacturing factory, we are committed to providing high-performance thermal insulation solutions for brands and business clients. This type of lunch bag features an advanced three-layer insulation structure: the outer layer is made of water-resistant and durable fabric for effective moisture and dust protection; the middle layer consists of high-density pearl cotton, offering excellent thermal retention and cushioning; the inner lining uses food-grade, oil-resistant aluminum film that is safe, easy to clean, and maintains heat or cold for extended periods. The structure is stable and built to last, ideal for food delivery, cold chain transport, and custom promotional applications. We offer flexible customization options including size, materials, logo placement, and compartment design. OEM and ODM inquiries are welcome.
Lining material selection
Custom food bags are built with a high-performance triple-layer structure, designed to balance durability, insulation, and food safety. The outer layer can be customized with materials like water-resistant Oxford fabric, eco-friendly RPET, or PU leather — depending on your branding and usage needs. The middle layer uses thick EPE (pearl cotton) for insulation and shock resistance. The inner lining options include food-grade PEVA, aluminum foil, or TPU — all leak-proof, easy to clean, and compliant with FDA/EU food contact standards.
With a wide range of materials available, we help you choose the best combination for your design, functionality, and budget — whether you’re building bags for meal delivery, lunch kits, or retail packaging.
Using seamless hot press technology
We use seamless hot press technology to create leak-proof linings that are durable, hygienic, and built for daily use. In our factory, high-frequency ultrasonic heat press machines (20–35kHz) and large-area sealing equipment bond PEVA, TPU, and aluminum foil linings without stitching. This eliminates needle holes, reduces contamination risk, and improves water-tightness.
Each batch undergoes leak-resistance tests (72-hour fill test), peel strength tests, and temperature durability checks (from -20°C to 80°C). Our process ensures consistent performance, even after 500+ cleaning cycles. Certified food-safe and ideal for both hot and cold use, this technology is especially suitable for insulated lunch bags, delivery pouches, and reusable packaging.
Handle and shoulder strap
Handle and shoulder strap components are produced in both China and Bangladesh factories, accommodating orders from small trials to large-scale production.
The Bangladesh factory focuses on mass production with monthly output over 500,000 pieces, offering competitive costs and ideal for food bags needing durable, easy-to-clean handles and straps.
The China factory provides flexibility for custom samples, small batches, and fast turnaround while maintaining consistent quality, suitable for food bags using water-resistant webbing, insulated padding, and other specialized materials.
Supports diverse webbing, adjustable buckles, padding, and reinforced stitching, offering custom food bag features like anti-slip, waterproof, and heat-resistant solutions for optimal functionality and comfort.

Real Feedback from Custom Food Bag Projects
Reliable service and thoughtful design — proven through real custom food bag feedback.
“We ordered a double-layer insulated lunch bag with PEVA lining and heat-press seams—stitching is tight, and there’s no leaking at all. Carrie also helped us adjust the logo printing method, so now it’s super clear and wear-resistant. Our clients love the final look.”
“This was our first time customizing lunch bags, so we were a bit unsure. But Carrie guided us through everything with patience. It honestly felt like she was part of our own team.”
“Cara replies fast and always double-checks the details. No pushing, no delays—just solid, professional support. The whole process went smoother than we expected.”
“The team really knows their materials. We used RPET fabric with an aluminum foil lining for our reusable food bag, and the cooling performance was better than expected. It even has a small mesh pocket for utensils—nice touch. Cara was great at handling the sample stage and made sure everything stayed on schedule.”
