The packaging of baby food and medical nutrition is always confronted with high sensitivity since it is directly related to individuals’ health, which brings significant challenges. Simple plastic films can be vulnerable to the sterilization process of these products and may become brittle or allow chemical compounds from the packaging to leach into baby food, leading to product contamination.
Supra Polymer Solution
Supra Polymer’s solution offers food-grade plastic films that include engineered films and wraps with sterilization capabilities, high barrier properties, and suitable printability. For example, containers with aluminum lids on multilayer films, multilayer films based on PP, PET, or PE that can withstand sterilization or pasteurization processes, shrink films or robust wraps for load stabilization in palletizing, and secondary protective layers for increased security. This solution enables producers to offer packaging that complies with hygiene standards, is user-friendly, recyclable or environmentally optimized, and resilient throughout the cold chain.
| Retort pouches (PET/Al foil/PA/CPP) | baby food purees |
| Sterilizable films (PA/PE, PP laminates) | baby food in flexible packs |
| PP-based multilayer films | sterilized milk nutrition packs |
| PET bottles with shrink sleeves | baby drinks and fortified juices |
| PE shrink films | multipacks of baby formula tins or jars |
| Pallet stretch wrap (LLDPE) | palletizing baby food cartons |
| Bubble wrap (LDPE blends) | protecting glass jars of baby food |
Features
Thermal or sterilization process stability
The films are designed to withstand increases in temperature or sterilization pressure without altering their structure or compromising the seal.
Very high barrier
The multilayer structure minimizes the ingress of oxygen or moisture and prevents the transfer of undesirable compounds from the package to the product.
Heat sealing
The packaging must have a safety seal during production and show clear evidence of tampering during use; this feature is particularly important for sensitive products like baby nutrition.
High printability
The packaging surface allows for the clear display of important information such as composition, usage instructions, medical warnings, and branding, which is highly effective in gaining the trust of parents and patients.
Logistics and recyclability
The packaging must be stable under low-temperature conditions and frequent handling, and its materials should be updated to allow for recycling or compliance with environmental regulations to reduce environmental impacts.
