You know, for businesses, besides the production of products, the packaging, transportation and preservation of products are also very important. Therefore, finding out and checking the quality of cartons for packaging needs is concerned by many people. And the content that is answered right in the article below we would like to be consulted carefully. Ensure that will help you better understand the type of carton with the right quality to meet standards for storing and moving products.
1. Standard carton quality check through the material
You know that checking the quality of cartons through the materials is an important criterion. We need to fully test the paper properties. Depending on the different types of paper, the criteria will be different. Typically, how to check the carton as follows:
- Standard carton for puncture strength.
- Carton standard for flat compressive strength, marginal compressive strength or flatness.
- Standard for paper weight, thickness and stacking capacity.
- Criteria for fat strength, platform strength and drop resistance.
- Whiteness standard.
Thanks to the inspection of the outer material of the carton it will help to attract customers' attention. A carton product with a beautiful, neat and solid look, of course, it will attract more customers if it is a rough and ugly carton.
In addition, if the product is stored inside a standard, quality carton, it also ensures its internal quality. As much as possible, any damage can cause damage to the product.
2. Check carton quality by whiteness
Here, checking the whiteness of cartons is to check the brightness and cleanliness of the paper. Specifically, the higher the whiteness and brightness of the paper, the sharper the contrast of the image, the more quality the printed image becomes.
You need to know that not all paper we can check the whiteness, but the test can only be done on pressed carton paper. You follow the steps below to check the quality of the caron barrel as follows:
- Use 10 sheets in each roll or gram of paper of 10x10cm size. But note that the test piece will be equal to the number of rolls or grams of paper.
Next, we will use a spectrophotometer to measure paper whiteness at 5 different positions on the same sample sheet. But note that only 1 sheet is measured at a time.
3. Check carton quality via flatness
Checking the flatness of carton paper is extremely important. Because by checking the flatness it is the most important determinant of the printability as well as the coating of the paper. We should also check only carton laminated paper. And follow the instructions as follows:
- For laminated cardboard or Kraft paper: Use 10 test pieces per roll or per gram. The minimum size should be 20x25cm and the number of test pieces will be in rolls or grams of paper. We should only weigh one set at a time.
- Apply carton paper test by paper conditioning method.
- Use some suitable equipment such as Parket or Shelfield or Print Surf ...
4. Check the quality of cartons by quantity of carton packaging paper
Here, the quantity of paper means how many grams of paper will weigh in the area of 1m2. And the quantity of carton paper will be measured in gsOm. This method of checking the quality of carton paper will be done as follows:
- For laminated carton paper or Kraft paper: Use 10 sample words per roll or per gram with the minimum size reaching 20x25cm. Note that the number of sample sets will be equal to the number of rolls or grams of paper and one bag will be weighed each time.
- With corrugated carton paper: Use 10 sheets per package with minimum size of 20x25cm and one set will be weighed each time.
5. Check carton quality by paper thickness
This is considered an extremely important criterion to check the quality of cartons. It is the thickness test that determines the strength of the carton and it will also have a relationship with the paper quantity.
We will use an electronic gauge or we can use a micrometer to check. The material tested here will be laminated carton paper, Kraft paper or corrugated carton board.
6. Check the quality of cartons based on the strength of the podium
This is the way to check the quality of the carton by the strength of the material when it is subjected to distributed pressure in an area of the material until it is torn. Purpose of calculating the bearing capacity of the carton.
We also need to check laminated cardboard, corrugated carton or Kraft paper with hydraulic pump or with ring clamps.
The presentation of the above article we hope that has helped you more understand how to check the quality of cartons. Look forward to more of our other articles to be updated with more important information.
