Heat without opening
Simplifies preparation for consumers and suits ready meals as well as chilled or frozen foods.
Microwave Self-venting Sticker
The Microwave Self-venting Sticker allows sealed microwaveable food packs to vent steam during heating, so consumers can heat food without peeling back the lidding film or opening the pouch.
Supplied in rolls for label applicators. Sample testing is recommended to confirm the packaging material, sticker position, food contents and microwave settings before production.
Microwave food packaging accessory
Microwave Self-venting Sticker
Heat microwave-ready foods without peeling back the seal. The controlled steam-release design helps vent steam during heating, simplifying use for consumers and making it easier for food processors and retailers to integrate the label into existing packaging operations.
- Microwave without opening the package
- Food-grade, heat-resistant material
- Compatible with labeling equipment
35 × 15 mm｜6,000 labels/roll
Sealed Microwave Heating
Heat without opening the package
Placed over the designated vent area of the package, the label releases steam as the food heats. Consumers do not need to peel back the lidding film or open the pouch. It is well suited to ready-meal packaging where convenience and smooth service matter.
- Fewer steps before heating—no peeling back or covering again
- Less handling around hot steam
- Suitable for convenience-store meals, chilled or frozen foods, and delivery meals
Steam Release Design
Controlled steam release for efficient heating and better texture
During heating, moisture inside the package turns to steam. The label releases steam at the designated vent point, making the process easier to control and helping the food retain moisture after heating.
Product data indicates that microwave heating time may be reduced. Actual results depend on serving size, moisture content, package structure and microwave settings, so testing with the actual product is recommended.
Production Line Integration
Roll-fed format for existing labeling lines
The labels are supplied in rolls and can be evaluated for use with existing labeling equipment. Food plants, central kitchens and high-volume packing operations should confirm the label size, application position and line speed, then run a trial on the actual equipment.
- Standard quantity: 6,000 labels per roll
- Labels unwind from the tail; 3-inch or 1-inch cores are available
- Run a trial on the actual labeler for specialty packaging or high-speed lines

Benefits & Values
Test every variable, from consumer heating to line integration
A successful application depends on more than adhesion. The packaging material, label position, food contents, heating conditions and production equipment all need to be checked together.
Shorter heating time
Product data indicates that heating time may be reduced by about 25%; actual results depend on the test conditions.
Maintain a moist texture
Controlled steam release helps reduce excessive drying or hardening after heating.
Packaging-line compatibility
Can be evaluated with most food pouches, lidding films and labeling equipment.
Applications
Applications for microwave food packaging
Venting performance varies with the packaging material and food contents. The applications below are common starting points; sample testing is still recommended before full production.
Ready meals and convenience-store trays
For microwave-ready meals that need quick heating with fewer steps for the consumer.
Hot-food vending and unattended retail
Suitable for smart vending machines, unattended retail and hot-food systems. The label and lidding film can be evaluated according to the storage conditions and microwave program.
Food plants and central kitchens
Suitable for high-volume packing, labeling and dispatch operations, with trials to confirm application stability and line speed.

Questions & Answers
Questions before implementation
Package structure, label position and food contents all affect performance. Phoenixes can help define the test conditions before production is evaluated.
Which packaging materials can be used with this label?
The label can be evaluated on many common food pouches and lidding films, including PP and PET. Special coatings, textured surfaces and low-temperature conditions may affect adhesion, so testing with the actual packaging material is recommended.
Will I need additional equipment on my production line?
The labels are supplied in rolls and can be evaluated with standard label applicators. Any changes to tooling, sensors or application settings must be confirmed against the existing equipment and line speed.
How long can the labels be stored?
The specification sheet states storage at room temperature and a shelf life of 24 months. Keep the rolls away from heat, direct sunlight, moisture and conditions that may affect the adhesive.
How do I validate the label with my microwaveable product?
Provide the packaging material, food contents, portion weight, microwave power and heating time. Testing with the actual product is used to confirm venting, adhesion, package appearance and food texture.
