How to distinguish the quality of paper cups
30 Aug 2019
Generally, at the time of purchase, the paper cup is mainly determined by observing the appearance characteristics, and the good paper cup generally performs the following test quality inspection: 1. Functional test: Test whether the paper cup can hold liquid, such as water. 2. Performance test: Test whether the paper of the paper cup is thick enough and not easy to be deformed. 3. Stress test (load test): Whether the liquid full of paper cups will be bad 4. Recoverability test: After the liquid is poured out, the paper cup can be restored to the original 5. Strength test: Whether the paper cup will soften and damage after a period of liquid. 6. Appearance test: Whether the shape of the paper cup is beautiful, the pattern is beautiful 7. Ease of use test: Whether the paper cup feels good when used, whether the taste is good, will not puncturing. 8. Safety test: After the cup is filled with water, the cup will be deformed to spill liquid onto the user.
Paper cup material

The production process of the cold drink cup: direct printing, die cutting, processing and forming, and spraying the food wax on the surface of the paper cup. The production process of the hot drink cup is made from the paper cup base paper through the PE film into paper cup paper, printing, die cutting and processing. 1. Composition of paper cup base paper (1) Base paper composition The main component of paper cup base paper is plant fiber. The production process is usually made from pulp fibers such as softwood and hardwood. It is pulped, refined, chemically added, screened, and then paper-cut. (2) Technical requirements According to the processing performance and performance of the paper cup, it is determined that the paper base paper must have the following technical requirements. 1 high water resistance The printed paper cups are required to have no water leakage and water leakage, so the paper base paper is required to have high water resistance. 2 easy to shape When making ...
Paper cup printing technology

Processing form Paper cup paper can be processed into a conical or cylindrical cup type, and can also be processed into other shapes of ice cream cup mechanism/tissue for daily use, so the paper cup is gradually becoming popular. Paper cups can be roughly divided into cold drink cups and hot drink cups according to their use. The quality requirements for paper cup materials vary depending on the application and the type of processing. In addition to meeting the requirements of packaging processing performance, paper cup materials must also have certain printability, and paper cup printing should also meet the conditions of heat sealing in paper cup processing. Hot drink cup It is usually used for the hot beverage packaging trade. The processing material is paper with single-sided PE composite, that is, single-sided coated paper. Generally, printing is performed on a non-PE surface and printed directly on the paper. Due to the needs of hot drinks, such paper cups need to have cer...
Several questions that must be paid attention to when buying paper cups
05 Aug 2019
There are many manufacturers of paper cups, but there are very few who can really think about them. We can see the paper cups with a price of about 4-5 minutes on the market. The quality of such paper cups is very poor. The profits of the manufacturers are indeed very limited. Even as low as one box of goods (2000), only 0.50-1.00 is earned. yuan. Such as A. Don't use cheap inferior paper cups: There are many manufacturers of paper cups, but there are very few who can really think about them. We can see the paper cups with a price of about 4-5 minutes on the market. The quality of such paper cups is very poor. The profits of the manufacturers are indeed very limited. Even as low as one box of goods (2000), only 0.50-1.00 is earned. yuan. Such low profits make it very doubtful that manufacturers can ensure hygiene and quality in every process they produce. Moreover, the paper used in the paper cup is easy to deform due to the thinness of the paper, and the hot water will be hot. ...
Engineering plastic grade PET is resistant to organic solvents
27 Jul 2019
Engineering plastic grade PET is resistant to organic solvents and has good weatherability. Disadvantages are slow crystallization rate, difficult molding process, high molding temperature, long production cycle and poor impact performance. Generally, the processability and physical properties are improved by means of reinforcement, filling, blending, etc., and the glass fiber reinforcing effect is obvious, and the rigidity, heat resistance, chemical resistance, electrical properties and weather resistance of the resin are improved. Adding a nucleating agent and a crystallization accelerator to improve the crystallization rate is slow. Adding flame retardant and anti-flammable dripping agent can improve PET flame retardancy and self-extinguishing. In addition, in order to improve PET performance, PET can be alloyed with PC, elastomer, PBT, PS, ABS, PA. PET (reinforced PET) is mainly processed by injection molding. Other methods include secondary processing methods such as extrusion, bl...
Daily storage method for paper cups
19 Jul 2019
Since the implementation of the national standard for disposable paper cups, paper cup printing has been clearly defined: the cup should be printed within 15 mm from the cup and the bottom of the cup should be within 10 mm from the cup. Moreover, when drinking water with a printed cup, the lips contact the cup, and the ink in the printed pattern may be ingested into the body. If the benzene-containing ink is used, it is not good for health; in addition, during packaging and storage, Paper cups are often one-piece, with a printed pattern on the bottom of the cup, and it is easy to smash the color onto the inner wall of the other cup. Daily storage methods and techniques for paper cups: 1. The paper cup should be placed in a dry place to prevent moisture, and the carton should be glued well. 2, the paper cup should be tightly sealed at each bag, do not leak air, this will also make the paper cup yellow; 3, paper cups must be boxed, can not be scattered outside, it will turn yellow...
