Introduction: Why Flexible Food Packaging Matters More Than Ever
In an era when consumers evaluate a product before they even open it, packaging has become a strategic asset for food brands. Packaging affects shelf life, food safety, logistics, brand perception, and ultimately purchase decisions. For food manufacturers, distributors, and private-label brands, the question is no longer whether packaging matters; the question is which packaging partner can deliver commercial reliability, regulatory compliance, and packaging that truly protects and elevates the product.
Qingdao Bomei Packaging specializes in one core mission: delivering high-quality plastic food packaging bags and vacuum food packaging bags that meet global food industry demands. With a modern 10,000+ m² facility, ISO9001-certified cleanroom workshops, integrated production lines (from film extrusion through pouch-making), and R&D focused on high-barrier materials, Bomei helps brands protect freshness, expand shelf life, and create packaging that sells.
This long-form guide takes you inside Bomei’s capabilities and explains — from a buyer’s perspective — what matters when choosing packaging for meat, seafood, dairy, snacks, frozen foods, coffee, pet food, and ready meals.
Today’s food-packaging decisions are shaped by several priorities that affect procurement, production, and marketing teams alike:
Freshness & shelf-life extension. Packaging must limit oxygen and moisture ingress to preserve taste, texture, and safety.
Food safety and regulatory compliance. Materials must be food-contact safe, traceable, and compatible with target-market regulations (EU, FDA, etc.).
Supply-chain resilience. Reliable lead times and consistent quality are non-negotiable.
Brand presentation. Packaging is often the first and most important brand touchpoint. High-quality printing and finishing matter.
Sustainability. Brands must increasingly demonstrate environmental responsibility while balancing cost and barrier performance.
Operational compatibility. Films, pouches, and vacuum bags must work seamlessly with existing filling and sealing lines.
Bomei Packaging approaches all these user-focused priorities with an integrated manufacturing model: a single supplier that handles material sourcing, co-extrusion/blown-film, high-barrier lamination, rotogravure printing, slitting and pouch-making, and strict quality control — all under ISO9001 cleanroom standards where appropriate.
Factory footprint and layout. Bomei’s production campus exceeds 10,000 square meters and is designed for flexibility and high throughput. Workflow and floor layout are optimized to reduce contamination risk and maintain efficient material flow from raw roll stock through conversion and packing.
Five specialized workshops focused on flexible packaging:
Film extrusion & co-extrusion — multi-layer film lines producing PE, PE/PA, PET/PA/PE, and other multi-layer constructions.
Printing — high-resolution rotogravure and flexographic capabilities for clear, photo-quality branding (up to 10 colors).
Lamination & barrier treatment — solvent-free and solvent-based lamination lines, including aluminum foil lamination for premium barrier performance.
Slitting & rewinding — precise slitting for automated bagging machines and pouch production.
Bag-making & pouch-forming — high-speed pouch machines, vacuum bag forming lines, zipper application, and specialty pouch finishing (windowing, valve insertion, tear notches).
ISO9001 cleanrooms are incorporated into key production areas where hygienic conditions are required — especially for vacuum bags intended for fresh meat, seafood, dairy, and ready meals. Cleanrooms minimize particulate contamination and ensure surface finishes meet strict customer and regulatory standards.
Throughput and scale. Bomei’s facility is engineered to support both high-volume continuous production and smaller, customized runs for market testing and seasonal promotions. A strong raw-material procurement system and inventory buffers reduce supply risk and shorten lead times.
Selecting the right film construction and materials is the single most important decision in flexible food packaging. Bomei’s R&D and technical teams develop multi-layer film architectures tailored to the product’s barrier, mechanical, and thermal requirements.
Core materials used:
Polyethylene (PE) — commonly used as the inner sealant layer (LDPE, LLDPE, HDPE).
Polyamide (PA / Nylon) — provides puncture resistance and mechanical strength (important for bone-in meat or frozen goods).
Polyethylene terephthalate (PET) — offers high clarity, printability, and structural strength.
Ethylene vinyl alcohol (EVOH) — excellent oxygen barrier when included in laminates.
Aluminum foil — the highest barrier, used in high-sensitivity products and products requiring full light and oxygen exclusion.
CPP (cast polypropylene) — used as a heat-resistant sealant for retort and high-temperature applications.
Typical laminate examples:
PET / AL / PA / PE — aluminum layer for highest barrier, ideal for long-shelf dry goods, some retort applications.
PET / PA / PE — strong barrier and puncture resistance for frozen meat and seafood vacuum bags.
PET / EVOH / PE — excellent oxygen barrier, commonly used for cheese and vacuum-packed products.
PE / PA / PE (co-extruded) — cost-effective and durable for many vacuum bag applications.
Design considerations for buyers:
OTR (Oxygen Transmission Rate) and MVTR (Moisture Vapor Transmission Rate) — low values increase shelf life.
Seal strength and seal temperature range — ensure compatibility with sealing equipment and desired cooking/retort processes.
Puncture resistance — critical for bone-in or irregular-shaped products.
Clarity and stiffness — affect retail appearance and machine handling.
Migration and odor testing — materials must not impart off-flavors or unsafe migration to food.
Below are the primary product families Bomei manufactures, each described with buyer-centric benefits and recommended use cases.

Quality for food packaging is non-negotiable. Bomei employs a layered quality management system that includes:
Incoming raw-material inspection (certificate of analysis, batch traceability).
In-process monitoring (thickness gauges, tension control, visual inspection).
Lab testing for barrier performance (OTR/MVTR), seal strength, puncture resistance, and color fastness.
Food-contact compliance — migration testing and odor testing to ensure no off-flavors or unsafe chemical migration.
Vacuum retention verification — simulated storage tests to confirm vacuum stability over time.
Retort stability testing for retort-qualified pouches.
Final batch release sampling with documentation for traceability.
ISO9001 certification underpins the entire system, and the facility can support buyer audits and third-party inspections. Bomei’s capability to provide documented testing and certificates is a significant advantage for buyers shipping to regulated markets.
Exporting food products requires packaging materials to meet the regulatory expectations of target markets. Bomei provides:
Food-contact grade materials with documentation supporting compliance with major standards (EU frameworks, FDA food contact criteria where applicable).
Certificate of Analysis (CoA) and raw-material traceability on request.
Support for buyer-specific testing (e.g., migration tests tailored to product chemistry).
Hygienic production environments (cleanrooms) for products that require stringent contamination control.
Buyers should discuss target-market regulations during the quotation stage so materials and process choices can be validated early.
Many buyers are balancing barrier performance with environmental goals. Bomei supports multiple sustainability strategies that are practical and commercially viable:
Mono-material PE solutions that enable mechanical recycling in regions with PE recycling streams. These solutions aim to maintain acceptable barrier properties while simplifying end-of-life processing.
Lightweighting — optimizing film structures to reduce material use without sacrificing performance.
Use of recycled content (post-consumer recycled, PCR) where product risk, barrier, and regulatory constraints allow.
Biodegradable/compostable film options for appropriate applications (note: these require careful selection and are not universally accepted by waste systems).
Energy efficiency and waste minimization in production — Bomei continually invests in process optimization to reduce scrap and energy consumption.
Buyer guidance: When sustainability is a priority, discuss end-of-life pathways, target markets’ recycling capabilities, and regulatory labeling requirements at the design phase.
Bomei’s customer workflow is built for clarity and predictable outcomes. Typical stages are:

Lower product loss — Improved puncture resistance and sealing reduce damaged goods and returns.
Reduced logistics cost — Lightweight films reduce transport weight and volume versus rigid packaging.
Improved retail performance — Premium printing and tactile finishes increase perceived value and shelf appeal, driving higher sell-through.
Reduced food waste — Better preservation and resealable features keep products fresher longer.
Examples of typical applications:
Frozen seafood exporter: Replaced commodity bags with a PET/PA/PE vacuum bag — result: zero leakage incidents during cross-ocean shipments and improved retail acceptance.
Meat processor: Implemented reinforced embossed vacuum bags for bone-in cuts — result: significant reduction in punctures and product loss during distribution.
Snack brand: Upgraded to high-resolution printed stand-up pouches with matte lamination — result: improved shelf presence and increased sales in premium retail channels.
Because you confirmed retort pouch capability is relevant, here’s a focused look at retort pouches — an advanced flexible packaging format that Bomei supports.
What is a retort pouch? Retort pouches are laminated flexible packages designed to undergo thermal sterilization (retort) at temperatures commonly between 121–135°C. The pouch maintains structural integrity and barrier properties after sterilization, enabling shelf-stable, ready-to-eat meals.
Benefits for food brands:
Shelf stability without refrigeration — reduces logistics complexity for many markets.
Superior convenience and portioning — ideal for single-serve or family meals.
Lightweight, efficient storage — lower shipping and warehouse cost than cans.
Premium presentation — superior graphics attract consumers.
Key technical attributes:
CPP or high-temp PE inner sealant to withstand retort temperatures.
Strong barrier layers (EVOH or aluminum foil) for oxygen and light exclusion if required.
Robust lamination and adhesive systems to avoid delamination under high heat.
Validated retort cycles — every product and pouch construction must be validated for the specific retort profile.
Applications: Ready meals, soups, sauces, pet food, pre-cooked rice and meals, and certain medical nutrition products.
When evaluating suppliers, procurement and product teams should verify the following:
Technical capability: Can the supplier develop the required multi-layer film and pouch design?
Food safety: Are production areas ISO9001 cleanrooms available for sensitive products? Are material CoAs and migration testing possible?
Barrier performance: What are the OTR and MVTR specifications of proposed structures?
Sealing strength & machine compatibility: Do the pouches and films match your sealing equipment and process temperatures?
Vacuum performance: For vacuum bags, how long does the vacuum hold under simulated storage?
Retort capability: If required, is the pouch design retort-compatible and validated?
Sustainability path: Can the supplier offer mono-material or recyclable alternatives?
Traceability & documentation: Does the supplier provide batch traceability and final inspection reports?
Lead times & contingency plans: How does the supplier handle raw material shortages or order surges?
Quality control & audit history: Can the supplier support audits and provide QC reports?
Bomei meets these criteria via integrated production capabilities, R&D support, documented traceability, and a willingness to collaborate on buyer-specific testing and validation.
