Misunderstanding: Someone uses their ears to hear if they have a sizzling sound to determine their thermal insulation performance. The ear can't hear whether it is vacuum.

3, plastic parts identification method: food-grade new plastic features: small smell, bright surface, no burrs, long service life is not easy to age.
