The cup cover material is divided into: PP, PS, and its production process is divided into injection molded cover and blister cover.
Commonly used specifications: 62mm 70mm 80mm 90mm
Packaging: 50 pieces/pack individually packaged, can also be packaged with paper cups for sale
The factory improves the process of paper cup equipment to match various interlocking groove cup lids, and tests the matching of paper cups and cup lids every shift.
Paper cup sample preparation: 10 consecutive samples, covering all molds of the paper cup machine.
Combined with the simulated terminal usage scenarios of domestic and foreign customers, a matching test of 9 large cup lids was established. The test liquid selected coffee, milk tea, etc., and the test temperature was 70-80 degrees. carry out testing.
1. Installation test: The lid fits perfectly with the mouth of the paper cup. The lid does not fall off. There is a crisp sound when the lid is buckled onto the cup. Rotate 360 degrees to check whether the lid is intact. After removing the cover, there should be no obvious squeeze deformation around the roll edge of the paper cup.
2.Standing test:
1）Pour 70-80 degree (coffee or water) into the cup two-thirds away from the inside of the cup. Tilt the paper cup at 45 degrees and let it stand for 10 seconds. Record the leakage at the inner seam. More than 3 drops are considered unqualified.
2）Tilt the cup with coffee at 45 degrees and let it sit for 15 minutes. Open the lid and visually check that there is no obvious deformation of the rolled edge and no dripping.
3. Tilt and rotation test: Inject 70-80 degree (coffee or water) into two-thirds of the cup, tilt the paper cup at 45°, rotate for 20 seconds (frequency about 40 times), record the dripping situation; more than 3 drops are considered unqualified
4. Swing test: Pour 70-80 degrees (coffee or water) into two-thirds of the cup, and shake the paper cup for 20 seconds (about 40 times). Tests are required in both X&Y directions. More than 3 drops are considered unqualified.
5.Lid test: Lift the lid (cup with coffee) with one hand, shake it up and down 3 times, 20-30cm away from the table; if the lid falls off, it will be judged as unqualified.
6.Push test: slowly push the cup with coffee upright for 1 time; the lid must not fall off
7. Re-closing the lid: Let the cup with coffee sit for 20 minutes to complete re-closing the lid.
8.Cup squeezing test: Hold the paper cup halfway, pinch the cup 1/3 of the way inward, and the cup lid will not fall off.
9.Two paper cups are bumped up and down 10 times without the lid falling off.
The main purpose of paper cup and lid testing is to ensure that the performance, quality, safety and reliability of paper cups and lids meet expected standards. The purpose of these tests is to verify the suction power and pore size of the product in actual use, meet consumer needs, and ensure that the product complies with relevant regulations and standards. Here are some possible testing purposes:
Leak-proof performance test: Evaluate whether the combination of paper cups and lids can effectively prevent users from liquid leakage under normal use conditions to ensure that they will not encounter slippage problems during use.
Heat resistance test: If the paper cup is used to hold hot beverages, test its performance under high temperature conditions to ensure that it does not deform, leak, or other problems.
Cold resistance test: If the product is used for cold drinks, test its performance in low temperature conditions to ensure that cracking or other problems do not occur.
Ease of opening test: Evaluate the ease of opening of the paper cup lid to ensure that users can easily open the lid and avoid unnecessary trouble.
Material safety testing: Ensure that the paper cups and lid materials used meet food safety standards and will not cause contamination to food or beverages to protect the health of consumers.
Environmental performance testing: If it has environmentally friendly properties, testing may include aspects such as the degradability and recoverability of materials to ensure that the product has a small impact on the environment during its life cycle.
Packaging stability testing: If paper cups and lids are used as packaging, testing may involve their stability during transportation and storage to ensure that the product is not damaged during the batch process.
Overall, these tests help manufacturers ensure that their cup and lid products perform well in the marketplace, meet customer expectations, and comply with relevant regulations and industry standards.
