Success in the food industry starts with the right packaging that protects products, preserves freshness, and reflects brand identity. At Packmaster, we run a transparent, measurable, and documented process, delivering performance and sustainability with our PP (Polypropylene) focused solutions.

1) Order Confirmation, Technical Brief, and File Control

• Technical brief: Product and portion, usage temperature (cold, hot, microwave), target shelf life, filling type (cold/hot-fill), logistics constraints, store or display scenario.
• Design files: Artwork and dieline (if printed), brand guide and PMS colors, label placement and QR.
• Material/grade (PP): Homopolymer vs. random copolymer, clarified PP for clarity, MFR; food-contact compliant color masterbatch.
• Compliance check: Our Declaration of Conformity framework, target market regulations (EC 1935/2004, EU 10/2011, EC 2023/2006 GMP, 94/62/EC) and 21 CFR/FCN for the USA; supplier CoA/CoC verification.

PP advantage: Microwave and hot-service compatibility (with suitable grade), lightweighting via low density, mono-PP design for recycling entry, RIC #5 marking.

2) DFM, Mold, and Production Preparation

• DFM and flow analysis: Wall thickness homogeneity, corner radii, rib and flange design, lock tolerances, feasibility of integral (living) hinge lids.
• Mold trials: T0/T1/T2 cycles to define process window, critical dimensions, and visual quality criteria.
• Approval gate: Golden sample and First Article Inspection, then written approval for serial production.
• Lightweighting study: Weight and CO₂ optimization using PP’s low density while preserving performance.

3) Production and Quality Assurance (SPC Supported)

• Process control: SPC with Cp/Cpk monitoring, OEE tracking, denesting speed optimization.
• Mechanical and functional tests: Top-load (stacking compression), drop and stack, warpage control.
• Seal architecture: Seal window (heat–time–pressure), seal strength, leak and tilt, burst.
• Conditions and usage: OTR/WVTR targets if required, microwave and hot-cycle validation.
• Hinge durability: Hinge cycle testing for hinged PP lids.
• Food contact: Accredited migration and sensory tests; NIAS risk assessment.
• Documentation: Batch and lot traceability, DoC and test reports.

4) Packaging, Labeling, and Shipment

• Case and pallet: Case dimensions and weight, TiHi (tiers × items), pallet configuration, stretch wrap and protection.
• Labeling: GS1/EAN-13/UPC barcode, lot and production date, RIC #5 (PP) and sorting instructions.
• Logistics docs: CMR/BOL, packing list, certificate of origin when needed, Incoterms agreement, shipment tracking.

5) Delivery and Aftermath: Support, CAPA, and Change Management

• Post-delivery check: Acceptance criteria review and performance feedback.
• Support and CAPA: RMA and claim handling, root cause analysis, corrective and preventive actions.
• Change notification: PCN and ECN for raw material, mold, or process; DoC and test updates.
• Transparency: Access to current DoC and reports via QR or link.

Sustainability: A Practical Roadmap

• Mono-PP and D4R: Labels, adhesives, and pigments selected for NIR sortability; clear RIC #5 guidance.
• Lightweighting: Reduced weight with maintained strength; material, logistics, and CO₂ gains.
• PCR-PP: Integrated on suitable lines to support circularity.
• Logistics efficiency: High nesting and optimized TiHi to reduce shipments and carbon impact.

Frequently Asked Questions

Why choose PP?

Suitable PP grades enable microwave and hot-service use, deliver lightweighting, allow mono-PP recycling entry, and offer hinged-lid ergonomics with single-SKU simplicity.

Which tests are performed?

Top-load, seal strength, leak and tilt, drop and stack, hinge cycle, OTR/WVTR, microwave and hot-cycle, plus accredited migration and sensory for food contact.

How is compliance documented?

With a Declaration of Conformity, accredited test reports, and traceability aligned to EU and US regulatory frameworks.
