From fine pharmaceutical powders to ready-to-drink cold-brew coffee, Composite Packaging quietly underpins global supply chains by tailoring layer counts, sealants, and print surfaces to each sector’s unique demands. Below are five industries where the same core technology is re-engineered rather than reinvented.
Agrochemicals
Granular fertilizers leave the plant in 25 kg woven PP/AL/PE bags. The outer woven layer provides tensile strength for stacking, while the aluminum foil core keeps moisture ingress below 0.1 g/m²/day, preventing caking during humid transit. A one-way PE valve allows dust-free discharge into blending hoppers.
Food & Beverage
Retort pouches for coconut milk pair PET for clarity, aluminum for oxygen barrier, and cast polypropylene for seal integrity. After 30 minutes at 121 °C, the Composite Packaging shows no delamination, cutting freight weight by 70 % compared with tin cans and reducing storage footprint in tropical warehouses.
Pet Care
Freeze-dried raw dog food ships in flat-bottom pouches built from PET/AL/LLDPE. The aluminum layer blocks light and oxygen, while the LLDPE sealant tolerates nitrogen flush without pinholes. Tear-notch placement is optimized for one-handed opening during walks.
Pharmaceuticals
Unit-dose desiccant sachets use PET/AL/PE Composite Packaging to keep relative humidity below 30 %, extending tablet shelf life in equatorial climates. Child-resistant tear notches and inline QR codes add compliance without secondary cartons.
Electronics
Anti-static bags for lithium-ion cells combine PET/AL/PE with an outer dissipative coating. Surface resistivity stays between 10^6 and 10^9 ohms, preventing electrostatic discharge during assembly or shipment.
Across these sectors, engineers simply adjust layer ratios, sealants, and print zones, turning Composite Packaging into a universal platform for safe, efficient, and lightweight containment.
