Explore our high-performance custom food packaging containers, barrier bags, and bakery boxes manufactured with food-grade certified materials for global export.
Precision barrier design is the cornerstone of maintaining lipid stability, moisture exclusion, and sensory crispness in commercial snack pouch manufacturing.
In the competitive global snack industry, potato chips, tortilla crisps, and extruded puffed snacks represent some of the most challenging products to package. The rapid degradation of fried snacks is primarily driven by two environmental catalysts: Moisture Vapor Transmission (MVT) which leads to loss of crispness, and Oxygen-Induced Lipid Oxidation which causes rancidity in delicate frying oils. As a premier ODM Chips Packaging Pouch Supplier & Service provider, Chaozhou Weiting Packaging Products Co., Ltd. (WTPack) engineers advanced multi-layer flexible barrier structures tailored to extend shelf life up to 18 months without synthetic preservatives.
Achieving commercial-grade shelf stability requires an intricate understanding of polymer physics and aluminum foil metallization. Standard single-layer plastics are porous to gas molecules. Our ODM engineering process utilizes co-extruded substrate matrices—integrating Biaxially Oriented Polypropylene (BOPP), Metallized Polyethylene Terephthalate (VMPET), Pure Aluminum Foil (AL), and Cast Polypropylene (CPP) or Linear Low-Density Polyethylene (LLDPE) sealant layers. This multi-ply construction creates a tortuous molecular path that dramatically restricts gas transmission.
Oxygen Transmission Rate reduced to < 0.5 cc/m²/24h via high-density VMPET & AL foil lamination.
Water Vapor Transmission Rate engineered down to < 0.1 g/m²/24h to eliminate moisture absorption.
100% UV light opacity prevents photo-catalytic degradation of unsaturated fatty acids.
How our 10,000 m² state-of-the-art facility in Anbu Town, Chaozhou delivers unmatched cost efficiency, scale, and technical precision for global procurement partners.
Located in Chaozhou, Guangdong—widely recognized as China's capital of food packaging manufacturing—our plant benefits from a hyper-integrated raw material supply chain. Film extruders, solvent-free adhesive formulators, electronic cylinder engravers, and masterbatch polymer producers operate within a 15-kilometer radius. This geographic concentration enables rapid prototyping cycles, reduced raw material lead times, and substantial cost savings that are passed directly to our ODM clients.
Equipped with high-speed Italian and domestic solvent-free laminating lines, our production workshop achieves bond strengths exceeding 2.5 N/15mm while maintaining zero solvent residue (< 3.0 mg/m²). High-precision electronic shaft rotogravure printing presses run at speeds up to 400 meters per minute with automated register control, guaranteeing microscopic graphic alignment, vivid brand rendering, and rapid completion of million-pouch orders.

Modified Atmosphere Packaging (MAP) displaces oxygen with food-grade N₂ gas. Our sealed pouch structures retain gas volume under varying atmospheric pressures during air transport or high-altitude logistics.
Elevate shelf presence with selective gloss/matte register varnishes, soft-touch velvet laminates, holographic stamping, and metallic window reveals that showcase product freshness.
Through inline flexural fatigue testing and vacuum chamber leak testing (ASTM D3078 standard), every production batch is checked to ensure zero micro-pinholes along seal seams and folds.
Navigating global legislative shifts, circular economy mandates, and sustainable packaging materials in the snack food sector.
Driven by the EU Packaging and Packaging Waste Regulation (PPWR) and corporate ESG goals, snack brands are shifting away from traditional multi-material laminates (such as PET/AL/PE) which are difficult to recycle in municipal streams. Our R&D team has developed high-barrier All-Polyethylene (PE/PE) and All-Polypropylene (PP/PP) pouch structures. Utilizing Machine Direction Oriented (MDO) PE films combined with EVOH ultra-thin barrier coatings, these pouches are 100% kerbside recyclable within RIC 4 streams while preserving product freshness.
To reduce reliance on virgin fossil fuels, WTPack integrates up to 30% ISCC PLUS certified chemically recycled Post-Consumer Recycled (PCR) resin into non-food-contact outer film layers. This ensures full food-contact safety compliance under FDA 21 CFR and EU Regulation No. 10/2011, while enabling brand owners to meet national plastic tax exemption thresholds across Europe and North America.

Expert insights from our senior packaging engineers regarding material selection, MOQ, testing standards, and ODM custom manufacturing.
For unprinted stock film rolls or standardized pouch sizes, our baseline MOQ starts at 10,000 pieces. For custom 10-color rotogravure printed pouches with bespoke dimensions, barrier layer specs, and custom surface finishes (such as spot matte/gloss or gold foil stamping), the typical MOQ is 30,000 to 50,000 pieces per SKU. This threshold is dictated by optimal film extrusion efficiency and rotogravure press setup waste reduction. However, we offer combined multi-SKU runs within a single order to help regional brands launch product variations efficiently.
High-altitude or air cargo transport creates a significant pressure differential between the gas inside a nitrogen-flushed pouch and the ambient environment. We prevent pouch bursting by engineering high-tensile sealant layers (typically customized metallocene LLDPE or CPP) with hermetic hot-tack strength. We perform rigorous vacuum bubble emission testing (ASTM D3078) and burst testing (ASTM F2054) on every production batch to verify that seal channels withstand internal expansion up to 45 kPa without micro-fissures.
Absolutely. All polymers, inks, adhesives, and metallized layers utilized in our Chaozhou production facility comply fully with U.S. FDA 21 CFR 177.1520, European Union Regulation (EU) No 10/2011, and GB 4806 standards for food contact materials. We issue batch-specific Certificate of Analysis (CoA), overall migration test reports from accredited third-party laboratories (SGS / TÜV Rheinland), and heavy metal compliance documentation (CONEG / RoHS) alongside every shipping container.
VMPET (Vacuum Metallized PET) is a thin layer of aluminum vaporized onto a PET substrate. It provides excellent flexibility, strong puncture resistance, and cost efficiency with an OTR of ~0.5-1.5 cc/m²/24h—ideal for standard snack chips with 6-9 months shelf life. Pure Aluminum Foil (AL layer, usually 6-9 microns) provides a 100% absolute barrier to light, oxygen, and moisture (OTR/WVTR approaching 0). AL foil is recommended for ultra-premium gourmet crisps, high-fat macadamia/nut snacks, or tropical export destinations requiring 12-18 months of guaranteed shelf stability.
For initial ODM orders, pre-press cylinder engraving and digital proof approval take 5-7 working days. Film extrusion, rotogravure printing, solvent-free lamination, curing (24-48 hours), and pouch converting require 15-20 days. Therefore, total production lead time is typically 21 to 25 calendar days post-sample approval. Repeat orders using existing gravure cylinders can be expedited to 12-15 days. Ocean shipping from Shantou or Shenzhen ports to North American or European main ports takes an additional 18-28 days depending on the maritime route.
