The entire production process of plastic packaging bags require numerical monitoring at critical links to ensure quality, such as the production of plastic bag materials -plastic film, the temperature of each stage needs to be accurate to enhance the strength of the film.

1. Glass -based temperature TG: Refers to the non -crystal part of the non -stereotypes includes the non -crystallization part in the crystalline polymer, from the glass state to the high elastic state or the transition temperature from the latter to the former. It is the minimum temperature of free movement of non -fixed polymer macromolecular segments, and it is also the upper limit of the work temperature of the product.

2. The melting temperature TM: For the crystal polymer, the three -dimensional remote order of the large -molecular chain structure is transformed into an disorderly adhesive temperature, also known as the melting point. It is the lower limit of the processing temperature of the crystallization polymer.

3, flow temperature TF: refers to the temperature that has changed from high elasticity to adhesive. It is the lower limit of non -fixed plastic processing temperature.

4. No flow temperature: The maximum temperature does not occur under a certain pressure. It is to add a certain amount of plastic to the ingredients at the upper end of the firing instrumental mold of the capillary flow instrument, and heated to a certain temperature. After the constant temperature is known for 10min, applies 50MPa constant pressure. The difficulty of raising is 10 degrees, and the same size constant pressure is applied after 10 minutes of thermal insulation. This continues until the melt flows out of the oral mold. It is not the flowing temperature of the material to reduce this temperature by 10 degrees.

5. Decomposition temperature TD: Refers to the polymer in the adhesive state When the temperature increases further, the degradation of the molecular chain will exacerbate, and the temperature of the polymer molecular chain is clearly degraded to the decomposition temperature.
