With the promotion of company specialization and productive cooperation between companies, the amount of raw material supply is also increasing. Quality of products, to a great extent, depends on the quality of materials supplied by suppliers, especially the packaging material. The quality of package has great chance to affect the quality of packed content and further cause quality problem of product. All of the above is great risk to companies in different industries, and companies shall take all possible measures to avoid the quality problems of product safety caused by package.
CONVEN provides professional packaging safety solution for companies from the perspective of packaging material.
Ink layer falling off is one of the common packaging problems. With this problem, the contents of hazardous solvent and heavy metal contained in packed content may exceed the standard required and do harm to health of consumers. Besides, it also may make the detailed product information on package surface illegible, causing inconvenience for sales of food, pharmaceutical and other products.
The two factors that may cause the ink layer falling off from package surface are environmental conditions in which the packages are placed and properties of packaging material.
1. When package containing packed content is placed in high humidity environment or contacts with alcohol, grease or other similar substances, the ink layer on surface of package may tend to fall off.
2. Problems of packaging material that cause the ink layer falling off may include:
1) Low packed content resistance of packaging material. For example, in case the grease resistance or acid/alkaline resistance of packaging material is poor, when used for packing packed content with such characteristics, ink layer may easily transfer to the packed content and thus causing the packed content contamination.
2) Low fastness between packaging material and ink layer. For example, the compatibility between ink and printing material is low, or surface property of printing material is below the printing requirement, which may cause the ink layer to fall off.
As to the possible factors that cause the ink layer falling off, CONVEN provides a complete packaging safety solution. From the quality control of purchased packaging material, CONVEN helps to select suppliers and improve packing processing techniques, aiming to prevent the ink layer falling off from package surface due to packaging quality problems. The solution consists of:
1) Hygienic condition test. For example, abrasion test of ink layer can be used to measure the transfer of ink layer when the packaging material is used to pack different contents.
2) Physical and mechanical performance test. For example, fastness test of ink layer and packaging material can be used to determine the abrasion resistance of ink layer. ?
Through the above mentioned performance tests, quality control of packaging material can be generally achieved, and thus ink layer falling off due to inferior quality of packaging material can be avoided.
Consisting of high precision intelligent testing instruments developed by Labthink, CONVEN Information System, and complete solutions for testing, diagnosis, quality analysis and quality control, CONVEN is a consulting packaging test service system, and has profound social value in respect of cost saving of plastic flexible packages consuming companies, product quality improving, food and pharmaceuticals safety guaranteeing.
