Hard Tray For Frozen Food

Shunxin Hard Tray For Frozen Food is made from food-grade PP sheets and formed through high-temperature heating and vacuum thermoforming. It can withstand temperatures as low as -30°C for long-term use, maintaining toughness without becoming brittle or cracking after freezing. The Hard Tray For Frozen Food features a thick rigid structure with a wall thickness of 0.3-1.2mm, providing excellent load-bearing and compression resistance. Even when fully loaded and stacked, the trays are less likely to deform or collapse.

The smooth surface is suitable for automatic sealing machines with film sealing, meeting the requirements of automated cold chain packaging. The tray supports customization from 1 to 10 compartments, allowing different food products to be separated and preventing them from sticking together. Shunxin factories strictly follow international quality management standards. The products comply with FDA and EU food contact standards. Customers are welcome to discuss specific application requirements for complete cold chain packaging solutions.

Exclusive One-Piece Stamping Structure

1: Cross Reinforced Bottom One-Piece Structure

Horizontal and vertical reinforcing ribs are simultaneously formed on the bottom of the tray to distribute stacking pressure evenly, preventing deformation under heavy loads.

2: Raised Sealing Edge One-Piece Design

The raised surrounding edges provide sufficient height to prevent frozen food juices from leaking out and contaminating storage environments.

3: Hydrophobic Embossed Anti-Slip Surface Process

The fine concave and convex textures on the tray surface reduce direct contact with food, helping prevent sticking and making demolding easier.

4: Nestable Synchronized Forming Structure

Empty trays can be nested together, significantly reducing cold storage space requirements.

5: Full Rounded Anti-Collision Edge Design

The thick and rounded edges provide better protection, reducing damage caused by impacts during production line transportation and forklift operations.

FAQ

Q1: Will the Hard Tray For Frozen Food become brittle or crack at -30°C?

A: No. Shunxin Hard Tray For Frozen Food is made from food-grade PP material. PP maintains good toughness in low-temperature environments and can withstand -30°C and below for long-term use. After freezing tests, the tray showed no cracking when bent under frozen tunnel temperatures.

Q2: What is the difference between PP and PET materials? Which one is better for frozen food?

A: PP material offers excellent low-temperature resistance (-30°C) with good toughness and crack resistance, making it the preferred material for frozen food trays. For frozen food, especially products requiring long-term frozen storage, PP material is generally recommended.

Q3: Can the Hard Tray For Frozen Food be used for microwave defrosting?

A: Yes. PP material can withstand temperatures up to 120°C and can be placed in a microwave for short-time defrosting and heating. However, it is recommended to use a low-power defrosting mode to avoid deformation caused by prolonged high-temperature heating.

Q4: Can this tray be used on automated packaging lines?

A: Yes. The Hard Tray For Frozen Food has a smooth surface and is suitable for automatic film sealing machines, making it convenient for use in automated cold chain packaging production lines.
