CPET trays

CPET trays have become an essential part of modern food packaging—trusted by meal prep companies, restaurants, and food manufacturers who need packaging that’s both safe and sustainable. These trays are built to handle extreme temperatures, protect food quality, and support Australia’s growing commitment to environmentally responsible packaging.

Whether it’s a ready meal, frozen dish, or takeaway product, CPET trays ensure your food stays exactly as intended — fresh, hygienic, and visually appealing.

When ready‑meals demand more than “just any tray,” our customised CPET trays deliver the performance your food‑business needs. Engineered for freezer‑to‑oven transitions, these trays withstand extreme temperatures from cold storage right through to reheating—retaining shape, sealing integrity and food safety under pressure. Explore our full Food Packaging Products range to see how CPET slots into a broader packaging system. And if you’re aligning materials with your environmental goals, check out our Sustainability page for insight into how choices like CPET support both performance and recycling standards.


The Secret Behind CPET’s Versatility

CPET (Crystalline Polyethylene Terephthalate) is a form of PET plastic that’s been crystallised to withstand a wide range of temperatures. That means a single tray can safely go from the deep freezer (-40°C) straight into a conventional oven (up to 220°C) or microwave without warping, leaking, or releasing harmful chemicals.

This durability makes CPET trays a perfect fit for today’s fast-moving food industry, where safety, efficiency, and sustainability must work together.


Why CPET Trays Are Trusted by Food Businesses

  1. Safe for All Conditions
    CPET trays retain their shape and integrity whether they’re frozen, reheated, or transported across long distances. This ensures meals reach consumers just as they left the kitchen.
  2. Freshness Locked In
    The non-porous nature of CPET provides an effective barrier against moisture and oxygen — two major culprits of food spoilage.
  3. No Cross-Contamination
    Because CPET doesn’t degrade under heat, it eliminates the risk of microplastics or contaminants mixing with food.
  4. Recyclable & Eco-Friendly
    CPET trays can be recycled through existing PET recycling systems, helping to reduce landfill waste and support circular economy goals in line with Australia’s national packaging targets.

Sustainability That Works in the Real World

Sustainable packaging is no longer just a buzzword—it’s a business imperative. Companies across Australia are moving toward eco-friendly materials that don’t sacrifice performance.

Carewell Group supports this movement with sustainability-focused packaging solutions designed to reduce waste while maintaining operational efficiency.

Unlike some biodegradable materials that struggle with durability, CPET trays strike the perfect balance — reusable, recyclable, and tough enough for industrial use.


Designed for Convenience and Safety

For meal prep companies, hospitals, or large-scale caterers, food packaging must perform under pressure. CPET trays simplify storage, reheating, and delivery with features that make daily operations smoother:

  • Compatible with heat-sealing film for leak-proof packaging
  • Stackable for easy storage and transport
  • Oven-safe, microwave-safe, and freezer-safe
  • Consistent performance under extreme temperature shifts

That combination of safety and convenience makes CPET a preferred choice for businesses that value both quality and sustainability.
