Custom High Quality Folding Silicone Food grade Storage Bags Manufacturing

Overview:

Crafted from 100% FDA-approved food-grade silicone, our reusable folding storage bags combine durability with eco-friendly functionality. Manufactured using precision silicone injection molding and reinforced seam-sealing technology, these lightweight bags feature a collapsible design, leak-proof closure, and withstand temperatures from -40°F to 450°F. Ideal for meal prep, travel, or sustainable kitchen organization, they’re dishwasher-safe and LFGB-certified for food contact safety. As a trusted silicone product factory, we specialize in OEM customization (sizes, colors, logos) and offer end-to-end services from design to bulk production. Elevate your brand with BPA-free, commercial-grade silicone solutions that reduce single-use plastic waste.

Characteristics:

Benefits of Our Food Bags:

1. Precision Injection Molding – Ensures seamless, leak-proof construction with uniform wall thickness for enhanced durability and flexibility.
2. Reinforced Seam-Sealing Technology – Utilizes ultrasonic or thermal bonding to create ultra-strong, tear-resistant joints that withstand repeated folding and washing.
3. High-Temperature Vulcanization – Optimizes silicone cross-linking during curing, guaranteeing thermal stability (-40°F to 450°F) and odor/taste resistance.
4. FDA/LFGB-Certified Material Processing – Rigorous purification and testing protocols eliminate BPA, phthalates, and contaminants, ensuring 100% food-safe compliance.

Quality Assurance:

Quality Assurance (QA) for custom high-quality folding silicone food-grade storage bags encompasses rigorous material validation, production process controls, and performance testing to ensure compliance with FDA 21 CFR, EU 10/2011, and LFGB standards. Key components include certified food-grade silicone verification via GC-MS (gas chromatography-mass spectrometry) for volatile organic compounds, tensile strength testing using Instron machines, and seal integrity checks with pressure decay testers. Accredited third-party labs conduct migration testing (heavy metals, phthalates) via ICP-MS (inductively coupled plasma mass spectrometry) and thermal stability assessments in climate chambers (-40°C to 250°C). Manufacturers must hold ISO 9001:2015, ISO 22000, and BRCGS packaging certifications, with batch-specific Certificates of Analysis documenting biocompatibility, odor resistance, and 10,000+ cycle durability. All processes adhere to cGMP protocols with full material traceability from resin to finished product.

Factory Show:

At our state-of-the-art manufacturing facility, we leverage advanced technologies including CNC machining, Mirror EDM, EDM, and high-precision slow-speed wire cutting (WC) to deliver exceptional accuracy in mold fabrication. Our production capabilities are further enhanced by 15 rubber compression molding machines and 2 LSR injection molding machines, allowing us to optimize both output and operational efficiency.

To uphold the highest quality standards, we employ an array of advanced inspection equipment such as 3D projectors, sealing testers, durometers, and elasticity testers. These tools are operated by a team of experienced and certified quality control professionals. Our processes are fully compliant with ISO 9001 and IATF 16949 certifications, ensuring the consistent delivery of reliable, high-performance components.

Additionally, we utilize automated systems including AutoDryers, high-speed doming machines, and precision die-cutting equipment to enhance workflow efficiency and maintain tight tolerances throughout the production cycle. These innovations enable us to achieve superior product performance, increase throughput, and ensure unwavering quality at every stage of manufacturing.
