The bag must work with the produce respiration rate

Fresh salad, herbs, cut vegetables, and whole produce release moisture and gases at different rates. Film permeability, perforation, seal style, pack size, temperature, and supply-chain duration should be developed around the actual product.

Anti-fog treatment can improve visibility, but it does not replace ventilation or temperature control. A shelf-life trial with the real produce is essential before approving production.

Do not trade shelf life for a clearer window

Retail teams want a clear view of the product, while technical teams need moisture and atmosphere control. The right balance depends on pack geometry, display orientation, refrigeration, and how quickly the product moves through distribution.

  • Produce type and cut state
  • Pack weight and headspace
  • Cold-chain temperatures
  • Target shelf life
  • Perforation or ventilation pattern

Verify claims and food-contact requirements

Terms such as compostable and biodegradable should only be used when the exact material, certification, disposal route, and market support the claim. The EU requires food-contact materials not to endanger health or alter food composition, taste, or smell.

Send the produce type, pack weight, current film or reference bag, storage temperature, target shelf life, packing equipment, destination market, artwork, and quantity.
