Half of the world's population comes into contact with 3M products every day, and 3M products such as post-it notes, reflective films, and anti-smog masks are all well-known by the public. Such a large and diverse company, but big but not chaotic, every product should not be underestimated, plastic wrap is one of them.
 
The 3M plastic wrap sold in the market is made in South Korea and is made of LLDPE. LLDPE is a kind of PE, which has better elasticity than PE, is not easy to break under the same tensile strength, has good heat resistance and low temperature resistance, and is suitable for -60°C-120°C environment. However, before putting plastic wrap in the microwave, you need to check the label on the package, but 3M plastic wrap does not have this label, so it is not recommended to put it in the microwave. Even if the plastic wrap is marked as microwave-safe and the heat-resistant temperature is below 140°C, when you put it in the microwave oven, do not cover the plastic wrap too tightly, keep a certain distance from the food, and the heating time should not be too long.
 
Other plastic wraps are single-layer designs, and the material qualitatively determines the viscosity and smoothness of the whole product, but 3M plastic wrap is three-layered, and the upper and lower layers are viscous, and the suction is better when pasting utensils; The middle layer has the characteristics of easy tearing and not tangling, and the cutting is smoother. Multi-layer film technology allows 3M plastic wrap to take advantage of its advantages and feel good to use.
 
The most expensive item in plastic wrap is from 3M, and the sliding knife design is faster than the sawtooth and dot break design, and the section is smooth and neat. It's just that the set costs 75 yuan, and the replacement is 54 yuan, which is not cost-effective.
