When it comes to packaging and product protection, one size doesn’t fit all. From preserving fresh food to organizing high-tech components, thermoformed trays provide tailored solutions across a wide range of industries. These trays combine precision design, cost-efficiency, and durability — making them a go-to choice for packaging engineers, brand managers, and production teams alike.
In this post, we’ll explore what makes thermoformed trays so effective, and how they’re being used across food, commercial, and industrial sectors.
But what exactly is rotomolding, and why is it so important in industries where high-quality, durable plastic products are a must? In this blog post, we’ll break down what rotomolding is, how the process works, and the benefits it offers to manufacturers and consumers alike.
What Is Thermoforming?
Thermoforming is a plastic manufacturing process that begins by heating a plastic sheet until it’s pliable. The sheet is then formed to the shape of a custom mold using vacuum, pressure, or mechanical force. Once cooled, the part is trimmed and finished, creating a strong, lightweight, and precisely shaped tray.
Compared to injection molding, thermoforming typically offers:
- Lower tooling costs
- Faster lead times
- Greater design flexibility for shallow or large parts
Food Packaging Trays: Keeping It Fresh and Safe
Thermoformed trays are widely used in the food industry due to their hygiene, clarity, and customizability. Common food applications include:
Ready Meals and Microwaveable Trays
These trays are heat-resistant and designed to go directly from shelf to microwave. They can include multi-compartment layouts to keep food items separated.
Fresh Produce, Meats, and Deli Items
Vacuum-formed trays help keep perishables fresh longer and can be used with modified atmosphere packaging (MAP) to further extend shelf life.
Bakery and Snack Packaging
Trays for cookies, pastries, or snack packs often feature custom cavities for aesthetic presentation and safe transport.
Materials commonly used: PET, RPET (recycled PET), polypropylene, and other food-grade plastics. Many options are recyclable or made with post-consumer content — supporting sustainability initiatives.
Commercial Applications: Product Display and Protection
For retail and commercial use, thermoformed trays serve dual purposes — protecting products during transport and enhancing shelf appeal.
Custom Insert Trays
Used in product kits or retail packaging (e.g., electronics, tools, cosmetics), these trays hold items securely in place and ensure a professional unboxing experience.
Retail Display Trays
Clear, high-gloss thermoformed trays can be used in clamshell packaging or countertop displays to make products stand out while keeping them organized.
Shipping & Logistics
Trays can be designed to nest or stack, saving space during storage and transport. Anti-slip textures and secure fits protect goods from shifting.
Industrial and Specialty Use: Durability Meets Precision
In manufacturing and technical fields, thermoformed trays are often engineered to meet strict performance requirements.
Material Handling and Dunnage Trays
Used to safely transport parts between workstations or facilities. These trays are reusable, tough, and often designed for robotic or automated handling systems.
Automotive and Aerospace Components
Precision-formed trays keep components organized and protected from damage or contamination during assembly.
Medical and Cleanroom Packaging
Thermoformed trays are ideal for single-use sterile packaging or reusable surgical instrument trays, often produced in ISO-certified cleanroom environments.
Specialty materials may include:
-
ESD-safe plastics for electronics
-
Flame-retardant or high-heat-resistant materials
-
Conductive or static-dissipative resins
Why Choose Thermoformed Trays?
Thermoformed trays aren’t just practical — they’re smart business. Here’s why:
- Highly customizable – Tailor every detail: dimensions, compartments, textures, stacking features, and branding.
- Fast production – Once tooling is complete, thermoforming supports high-volume output with consistent quality.
- Lightweight and cost-effective – Trays reduce shipping weight and eliminate the need for multiple packaging components.
- Sustainable options – Many trays are recyclable or made from recycled content, helping reduce environmental impact.
Partner with a Thermoforming Expert
Choosing the right partner for thermoformed tray design and production can make all the difference. Look for a manufacturer who offers:
- In-house design and prototyping
- Material expertise across food-safe, industrial, and specialty plastics
- ISO-certified quality systems
Scalable production capabilities for short runs or high-volume orders
