Industry problems directly: microwave heating always burst bags? Analysis of microwave exhaust bag how to break the gam

Real scene questioning:‘Why is the instant food packaging clearly labelled ‘microwaveable’, when heated or burst all over the stove grease stains?’

Traditional packaging due to uncontrolled internal pressure and exhaust lag:

❶ Bag bursting rate >15% (third-party lab data), with the risk of scalding;

❷ Separation of wet and dry food: loss of moisture up to 30%, Waterloo-style decline in taste;

❸ Wretched opening: 88% of users need scissors to assist, workplace/outdoor scene is extremely inconvenient.

Microwave exhaust bag core technology disassembly

Active Pressure Relief System】W-shaped Laser Scoring + Double Valve Membrane Double Insurance

✅ Laser micro-engraving technology

· 2 groups of W/S shaped indentations preset per bag, burst pressure threshold ≤ 0.1MPa (conventional membrane > 0.3MPa)

· Intelligent gradient rupture: directional cracking when air pressure reaches the critical point, noise reduction of 20dB

✅ Dual exhaust valve redundant design

· Upper/lower end valve membrane synchronous pressure relief, even if the single valve failure can still ensure safety

· Laboratory test (GB/T 21302): 800W high fire for 3 minutes with zero bag bursting.

Performance comparison

Three generations of upgrades: from passive response to active protection

1. Accurate pressure relief - hear the air pressure and say ‘no’.

· Pressure sensor test: 700W heating 60 seconds to trigger the expansion of the scoring, 3 seconds faster than conventional packaging to start the exhaust

· The industry's first differential pressure visualisation test: the pressure curve is smooth and spike-free throughout the heating process.

2. Water-locking expert - the guardian of freshness in microwave cooking

· Low water vapour escape, retaining 86% of the original juices.

· Blind consumer test: the taste of rice after reheating is close to that of rice cooker (satisfaction 9.2/10)

3. Reheat & Eat - The Ultimate Solution for Lazy Economy

· Weak heat seal pressure auto open design:

· No auxiliary tools required, office workers lunch efficiency increased by 65 per cent

Scenario validation: lab data to 10 million production lines

Scenario 1: Prepared dish microwave ready to cook

· Sweet and sour pork retains 92% of its crispiness after heating and improves juice adherence by 40%.

· Production line test: bag reworking rate reduced from 1.2% to 0.05%, saving 3 hours of oven cleaning time on average per day

Scene 2: Cold chain food emergency room

-10℃ frozen pizza directly high fire for 4 minutes, no local overheating scorching phenomenon

Feedback from · merchants: repurchase rate generated by customers due to good heating experience ↑29%

Scenario 3: Aseptic delivery of medical nutritional meals (Abbott, Nutricia)

· Passed 121℃/20min sterilisation test with 100% bacteria barrier rate (ISO 11607 standard)

· Chemotherapy patients' family research: ’Warm food packaging that can be opened with one hand is so important!’
