Introduction
With the rapid growth of ready meals, frozen food, meal preparation, and takeaway packaging markets, PP microwave safe food containers have become one of the most popular plastic packaging solutions. Many food packaging manufacturers are looking for the right equipment to produce PP meal trays, microwaveable food trays, and PP food containers with lids.
So, what machine can make PP microwave safe food containers?
The answer is a PP food container thermoforming machine. A professional positive and negative pressure thermoforming machine can transform PP sheets into high-quality microwave-safe food containers with excellent strength, appearance, and dimensional accuracy.
What Is The Best Machine For PP Microwave Food Container Production?
The recommended equipment is a 3-station positive and negative pressure thermoforming machine, such as the TZ Machinery SWT-7565 thermoforming machine.
This type of machine uses PP sheet as raw material and completes the entire production process:
Sheet feeding → Heating → Positive & negative pressure forming → Punching → Stacking
The SWT-7565 thermoforming machine is suitable for producing:
- PP microwave food containers
- PP ready meal trays
- Frozen food trays
- Meal preparation containers
- Takeaway food packaging
- Disposable food containers
The machine supports various materials including PP, PS, PET, PVC, and PLA, making it flexible for different packaging applications.
Why Use Positive And Negative Pressure Thermoforming Technology?
For microwave-safe PP food containers, product strength and wall thickness consistency are very important.
Compared with traditional vacuum forming machines, the SWT-7565 uses positive pressure + negative pressure forming technology. This dual-pressure forming method improves:
- Container shape accuracy
- Corner definition
- Wall thickness distribution
- Deep drawing performance
The machine is equipped with Japanese CKD pneumatic valves, allowing stable forming performance even for deep containers up to 120mm height.
Key Advantages Of SWT-7565 PP Food Container Making Machine
1. High Precision Servo Drive System
The SWT-7565 adopts a full Delta servo drive system for mold movement, sheet feeding, stretching, and stacking.
Servo control provides:
- Accurate sheet positioning
- Lower material waste
- Stable container quality
- Higher production efficiency
All four motion axes are controlled by Delta servo motors with closed-loop positioning technology.
2. Strong Mold Clamping Structure For 24/7 Production
Food packaging factories usually require continuous production.
The SWT-7565 uses a one-piece cast mold table with crankshaft and 5-point clamping structure, which distributes punching force evenly and improves machine stability and mold lifetime.
With an 80-ton punching force, it is suitable for high-speed PP food container production.
3. Precise Heating Control For PP Sheets
PP materials require accurate temperature control during thermoforming.
The machine uses independent heating brick temperature control with PID adjustment, helping reduce:
- Uneven heating
- Material waste
- Product deformation
This is especially important when producing thin-wall microwave food containers.
SWT-7565 Thermoforming Machine Technical Highlights
- Forming area: 760 × 650 mm
- Maximum forming height: 120 mm
- Speed: 5-45 cycles/min
