plastic drinking cups are very common in our daily lives, whether in restaurants, hotels, or in everyday use.
Generally, when manufacturers produce plastic water cups, they will make relevant material distinctions at the bottom of the water cup. The following 7 kinds of signs are the serial number signs that we will come into contact with in our daily life to distinguish each different plastic
No. 1: PET, used in mineral water bottles, cola bottles, etc.

How do we choose plastic water cups?
Since all materials of plastic water cups are introduced as above, let’s talk about the most commonly used water cup materials in our daily life.
The common plastics material in daily drinking cups are PC, PP, and Tritan
PC and PP with boiling water are completely no problem, and a good plastic cup with strict procedures does not release BPA.
PP and Tritan are both the main plastic material for making baby bottles
Tritan is currently the designated baby bottle material in the United States. It is a very safe material, and there will be no precipitation of harmful substances.
PP plastic is dark gold material and is the most commonly used material for baby bottles in our country. It can be boiled at a high temperature for sterilization and is very resistant to high temperature.
So how to choose the material of the water cup?
The plastic water cups that meet the national regulations are actually safe to use. It is only necessary to compare these three materials and make them a priority level.
Safety performance: Tritan > PP > PC;
Affordable: PC > PP > Tritan;
High temperature resistance: PP > PC > Tritan
Second, according to the adaptative temperature selection
To put it simply, it is for what beverages we usually contain;
We just have to ask ourselves one question: “Shall I fill it with boiling water?” heat resistance has always been a prerequisite for selection.
Install: choose PP or PC;
Not installed: choose PC or Tritan;
Three, according to the use of choice
For your lover to go shopping as a portable cup, choose a small-capacity, exquisite, compact and leak-proof;
For those who travel frequently and run long distances, choose a large-capacity, wear-resistant water cup;
For daily use in the office, choose a cup with a larger mouth;
Choose different parameters for different purposes, and be precisely responsible for the water cup you use for a long time.
Fourth, according to the capacity selection
Everyone’s water intake is inconsistent. Healthy boys consume 1300ml of water per day, and girls consume 1100ml of water per day.
The following is a general version of the selection capacity method
350ml – 550ml for baby, short trip
550ml – 1300ml Home Use, Sports Hydration
1300ml – 5000ml Long-distance travel, family picnic
Five, according to the design choice
The design and shape of the cups are different, and it is very necessary to choose a cup that is suitable for your use.
Although some plastic water cups are particularly beautiful, many designs are ineffective. Try to choose a water cup that meets your needs.
It will be better for girls to choose a water cup with a straw mouth, and it will not stick to lipstick.
Boys often travel or exercise and choose to drink directly, and they can drink water in large gulps.
And when choosing, consider portability; Check plastic cups for hooks or lanyards.
