Engineered paper packaging for fresh fruit and vegetables—from farm to DC to store. We design die-cut trays, telescoping boxes, RSC/HSC shippers, and SRP display trays with the right flute, ventilation, and moisture resistance so loads stack safely and scan clean through the cold chain.
How do you choose board grade and flute?
Concise lede: Match flute and grade to unit weight, humidity, and stack height; set ECT/BCT targets under cold-chain conditioning.
Selection guide
- Flutes: E (print, short shelves), B (common produce trays), C (higher cushion), BC (double-wall for heavy stacks).
- Strength: specify ECT (typ. 32–44 ECT single-wall; 48–61+ ECT double-wall) and confirm BCT by stack map.
- Conditioning: validate after 48–72 h @ chilled/high RH to reflect real routes.
- Joinery: glue-tab die-cuts for speed; stitched bliss for very heavy packs.
How do ventilation and moisture protection work?
Concise lede: Use patterned vent holes to control airflow and field heat; combine water-resistant (WRA) coatings or recyclable wax alternatives to resist moisture without hurting recyclability.
- Open area: typically 3–8% of panel surface; align with precool airflow; avoid weakening corners.
- Hole geometry: oblong/slot vents near corners for stack paths; berry lids use micro-vents.
- Moisture systems: WRA/dispersion coatings or film-lam spot protection; favor wax-alternative for fiber recovery.
What about food safety and compliance?
Concise lede: Use food-contact-safe paper/inks, GMP/HACCP production, and clean storage. We implement your compliance program and documentation.
- Materials: food-safe paper & water-based inks/adhesives; low-odor specs.
- Process: pest-control, segregation, traceability (lot IDs).
- Standards: align to your HACCP/GMP/BRCGS Packaging requirements; we do not offer legal advice.
How do you handle printing, labeling, and traceability?
Concise lede: High-read flexo or litho-lam for branding; ITF-14/GS1-128 for cases; PTI fields or QR/Datamatrix for traceability.
- Branding: 1–3 color post-print flexo for cost; preprint/litho-lam for high graphic.
- Codes: ITF-14 on sides; GS1-128 when needed; keep quiet zones ≥ 2.5 mm and off corner posts.
- Labels: cool-surface, matte zones; condensation-resistant adhesives.
How do you palletize for cold chain?
Concise lede: Standard footprints and interlocking patterns protect BCT under chill and humidity.
- Footprints: NA pallet 48×40 in; common case bases 24×16, 20×16, 24×12 in. EU: 600×400 / 400×300 mm.
- Stacking: column or interlock per design; use corner posts/top frames for tall stacks.
- Load securement: stretch wrap + top sheet; vent alignments maintained.
Concise lede: 100% recyclable designs with FSC options, fiber optimization, and wax alternatives that withstand moisture.
Options
- Right-weighting by flute/liner; high-performance liners to replace wax.
- Mono-material solutions—avoid plastic films where possible.
- Clear recycling marks; supplier chain documentation available.
