Among the huge-scale food market, packaged food, with the developing of modern food processing industry and sales industry, as well as the improving of living quality and standard, is accepted and favored by more and more people. Proper packaging can not only strengthen the hygienic safety, extend shelf life of product, and facilitate the carrying, eating and storing, but also increase the attractiveness of product. However, if packaging material is of inferior quality, it may cause food safety problem and do harm to consumer health, and further result in immeasurable loss for food companies.
CONVEN provides professional packaging solution for food company from the perspective of food packaging.
Oil penetration refers to the penetration of oil and grease or their processed products through the package. The problem, mainly due to the quality of packaging material, often occurs at the heat sealing area or outer layer of flexible package. Quality problems that cause the oil penetration may include:
1) Low quality of packaging material. For example, low oil/grease resistance of flexible packaging material may lead to the oil penetration through the package. Besides, if compound strength of applied flexible packaging material is low, film layers may be liable to separate from each other, causing the oil penetration problem.
2) Poor seal performance. For example, improper heat seal may result in poor seal performance at the sealing area, and further leads to oil penetration problem.
3) Low physical and mechanical performance. For example, if packaging material is low in flexibility and puncture resistance to packed content, or low in flex resistance and compression resistance, there may be pinholes or crease appeared on package during storage or transport, even the package may break. If such problems are not discovered in time, oil penetration problem may occur to the package.
In order to prevent the happening of such problem, food companies shall start from selecting proper type of packaging material for the packed content. And then solve oil penetration problem step by step through quality control of packaging material. 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 oil penetration due to packaging quality problems. The solution consists of:
1) Seal performance of food package. For example, by conducting seal and leak test, and burst pressure test, leaking problem as well as leaking position can be detected in time, if any, and the area of package with low mechanical strength can be positioned. Besides, heat seal strength test can determine whether heat seal strength meets requirements of packed content, and find out the position where the heat sealing is not proper.
2) Physical and mechanical performance. For example, oil/grease resistance, tensile strength and elongation rate at break, puncture resistance, pendulum impact resistance, peel resistance, etc, test of which respectively or in combination can be used to evaluate whether the physical and mechanical performance of package such as oil resistance, flexibility, puncture resistance and flex resistance can meet the requirements of packing and transport
Through the above mentioned performance tests, quality control of packaging material can be generally achieved, and thus oil penetration problem 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.
