In 2023, an international coffee chain was forced to recall millions of its products due to leakage of disposable cups, which directly caused a large loss. Cases like this happen every day in the foreign trade industry - seemingly simple disposable cups can become "hidden bombs" in your supply chain. As a specialized third-partyinspection of goodsIndustry "Inspector Online", we know that the disposable cups of the inspection is far from simple sampling, but the key link of trade security. This article will take you to an in-depth analysis of the core of the disposable cups of goods inspection, master these methods, you will be able to avoid 90% trade disputes!
I. Requirements for inspection of goods
1. Material requirements
The material of disposable cups must comply with the safety standards of relevant countries and regions, such as the CE standards of the European Union and the FDA standards of the United States. Common materials are paper and plastic, paper cups of paper should be odorless, no fluorescent whitening agent; plastic cups are usually made of PP (polypropylene) to ensure non-toxicity, high temperature resistance, and will not release harmful substances in the process of use.
2. Appearance requirements
The surface of the cup should be flat and smooth, without wrinkles, breakage or stains. The mouth and bottom of the cup should be rounded and regular, without burrs, to avoid scratching the user. Patterns and text printing should be clear, firm, no blurring, color loss phenomenon.
3. Dimensional requirements
It should be inspected strictly according to the dimensions specified in the order, including the height, caliber and capacity of the cups. The size deviation should be within the allowable range to ensure that the cups can be used and packaged properly.
4. Physical performance requirements
Paper cups should have good stiffness and water resistance, in the holding liquid will not appear soft, leakage phenomenon; plastic cups should have a certain toughness and impact resistance, not easy to break. At the same time, the sealing of the cup should be good to prevent liquid leakage.
Two,Methods of inspection
1. Sample testing
In accordance with internationally recognized sampling standards, such as ANSI/ASQ Z1.4, a certain number of samples are randomly selected from the whole batch of goods for testing. Sampling should ensure that the samples are representative and cover different production batches, packaging units, etc.
2. Appearance inspection
Conduct a preliminary inspection of the cup by sight, smell and touch. Observe whether the appearance of the cup meets the requirements, smell whether there is an odor, touch the mouth and bottom of the cup to feel whether it is smooth and burr-free.
3. Dimensional measurements
Using calipers, measuring cups and other tools, accurately measure the height, caliber, capacity and other dimensional parameters of the cups and compare them with the order requirements to determine whether they are within the allowable deviation.
4. Material testing
For the inspection of materials, professional testing equipment can be used. For example, use the fluorescence detector to detect whether paper cups contain fluorescent whitening agent; through the composition analysis instrument to determine whether the plastic cups are made of PP, and whether they contain harmful substances.
5. Functional testing
Conduct a water resistance test, paper cups filled with a certain amount of water, placed for a period of time to observe whether the leakage; high-temperature resistance test on plastic cups, pour hot water to see whether the deformation, the release of odor. Drop test can also be conducted to check the impact resistance of the cup.
