In recent years, quality safety problems of food and pharmaceuticals are frequently reported. The public has always been focusing on the quality of food and pharmaceuticals, but ignoring that inferior package quality is also one of the critical factors affecting the quality of product and leading to safety problems. With the fast developing of consumer goods industry, package has been playing an important role in value adding of product in sales. For example, well packaged product can attract more attention of consumers and stimulate their purchasing desire. However, as the outwear of packed content, the fundamental function of package is to ensure the safety of packed content.
CONVEN provides professional packaging safety solution from the perspective of packaging material.
Peculiar smell of food is one of the common quality problems of package containing packed content. Packed food with peculiar smell is not suitable for eating, or it may do harm to the health of consumer. Besides, package itself sometimes may also smell peculiar, which would intensify the peculiar smell of the product. The product is not supposed to have such smell. Sources of product peculiar smell may include packaging material and peculiar smell in external environment. Packaging quality related aspects causes of peculiar smell of food and pharmaceuticals include:
1) Peculiar smell of packaging material. For example, if the solvent contained in packaging material is not completely volatilized, the residual solvent may transfer into the packed content, causing the peculiar smell. Also, if quality of raw packaging material and additive is low, or the additive is used with exceeding quantity, the package containing packed content may smell peculiar sometime later.
2) Low barrier property. For example, in case the gas resistance of packaging material is low, peculiar smell in the environment may transmit into the package when stored in such environment, resulting in the peculiar smell of packed content.
3) Poor seal performance. For example, improper heat seal may result in poor seal performance at the sealing area, and as a result ambient peculiar smell may transmit into the package from the sealing area.
4) 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, packed content may contact with peculiar smell in the environment.
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 peculiar smell of packed content due to packaging quality problems. The solution consists of:
1) Barrier property of packaging material. For example, whether barrier property of applied packaging material meets requirements of packed content can be verified by oxygen transmission rate test and water vapor transmission rate test.
2) Seal performance. 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.
3) Physical and mechanical performance. For example, tensile strength and elongation rate at break, puncture resistance, pendulum impact resistance, peel resistance, etc, of which the combination can be used to evaluate whether the physical and mechanical performance of package such as 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 peculiar smell of packed content 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.
