What are the raw materials of plastic packaging boxes?

In the plastic packaging industry, the more popular packaging materials today are PET, PS and PP. Strawberry packaging boxes, blueberry packaging boxes, and other blister packaging boxes made of these materials have different characteristics. , The appearance is exquisite, the practicality is strong, and it is also very safe. Don't worry about the video being contaminated. Since everyone knows these materials, but is it not clear about their performance, then look down and tell you.

The raw materials of the plastic packaging box are as follows:

1. Polypropylene (PP)

Performance characteristics: Polypropylene is a very light kind of general-purpose plastics, and its heat resistance is very high among general-purpose plastics. It can be used for a long time at 100℃～120℃. High crystallinity, tensile strength and hardness are better than polyethylene, moisture resistance, water resistance and prevention of odor penetration are good, and it can be heat sealed. Very good resistance to bending fatigue strength, resistance to acids, alkalis, salt solutions and most organic solvents such as polypropylene packaging boxes below 80 ℃ take advantage of this feature. Poor cold resistance and aging resistance, poor air tightness, not suitable for use at low temperatures, and easily affected by light and oxygen. Surface treatment is required before bonding or printing.

2. Polystyrene (PS)

Performance characteristics: colorless and transparent, odorless and non-toxic, good coloring and printability, low water absorption, good dimensional stability, rigid without ductility. Resistant to organic acids, alkalis, salts, lower alcohols and their aqueous solutions, low impact resistance, low surface hardness, easy to scratch and sanding; poor moisture resistance, heat resistance, easy to be divided by many hydrocarbons, ketones, fatty acids, etc. And soften.

3. Polyethylene terephthalate (PET)

Performance characteristics: very good mechanical strength, good hardness, wear resistance and folding resistance, good heat and cold resistance, good moisture resistance, air tightness and excellent resistance to odor penetration, and resistance to weak acids , Weak alkali and most solvents, good oil resistance, suitable for printing, not resistant to strong alkalis, strong acids, chlorinated hydrocarbons, etc., also have corrosive effects on it.
