What are the core differences between pet and pp materials in cold drink scenarios?
| Comparison dimension | Pet (polyethylene terephthalate) | Pp (polypropylene) |
|---|---|---|
| Transparency | High transparency, suitable for displaying the color of drinks | Translucent or frosted, with low light transmittance |
| Temperature resistance range | About -20℃~65℃, suitable for cold drinks | About -20℃~120℃Suitable for both hot and cold use. |
| Hardness and feel | Harder, with a stiff cup wall. | Soft and flexible to the touch. |
| Barrier | Good gas barrier properties, keeping air and freshness | Excellent water resistance, average air resistance |
| Cold drink suitability | High-quality, the preferred material for cold drinks. | Medium, suitable for cold drinks but lacks clarity. |
| Common uses | Milk tea cups, cold drink cups, fruit tea cups | Cup lids, hot drink cups, lunch boxes |
| Recycling logo | Number 1 | No.5 |
For cold beverage applications, pet cups offer superior clarity and rigidity, allowing for better display of the drink's layers and enhancing the brand's visual appeal. while pp cups boast a wider temperature resistance range, they lack the transparency and stiffness of pet in purely cold beverage settings.In [1688](https://www.1688.com/Search for "pet disposable cups" or "pp disposable cups" to find a wealth of comparison samples with the same specifications.
What are the quality differences between injection molded cups and blister cups?
In addition to the material, the molding process also affects the quality and cost of the cup.
| Craftsmanship dimension | Injection molding | Blister molding |
|---|---|---|
| Uniformity of wall thickness | Good, the cup wall is consistent. | There may be differences in thickness between the bottom and side walls |
| Surface finish | Smooth, suitable for printing | Relatively average |
| Mold cost | Higher | Lower |
| Suitable for bulk | Large quantities are more economical. | Small batch flexible |
| Common products | Pp cup lid, thickened cup | Pet cold drink cup, thin wall cup |
| Production speed | Single-mode cycles are short and highly efficient. | Continuous production, large capacity |
Taking xuchun plastics as an example, the factory is equipped with fully automatic high-speed sheet molding machines, injection molding machines, vacuum forming machines, and high-end imported cup forming lines, enabling simultaneous coverage of both injection molding and vacuum forming processes.Its pet cold drink cups mostly use blister molding technology, with thin walls and high transparency; pp cup lids use injection molding technology, which has better sealing and durability.When making a choice, buyers should consider the cup's material and intended use to determine the appropriate manufacturing process, rather than simply assuming one process is universally superior to another.
