The exquisite fruit soft cans packaging is light, unbreakable, strong in three-dimensional and can meet the packaging requirements of the canned industry and become the highlight of the industry development. With the rapid promotion and application of soft canned fruit packaging in China, the question of how to carry out quality control has followed.
Jinan Languang has specially provided packaging quality control solutions for the fruit soft canned industry, and designed and provided equipment for opening force, sealing, pressure resistance, oxygen barrier, moisture resistance, and heat sealing performance tests. At present, these devices are widely used in Wuling Taixin, Ningbo Baoda, Ningbo Baoyu, and Zhoushan Weizhou Food Company.
In order to further meet the needs of the market, the relevant inspection projects of the industry are now summarized as follows in order to provide more technical support for more fruit soft canned enterprises and packaging material supply manufacturers.
1, packaging sealing test
The sealing performance of the package is an important indicator for the detection of fruit soft cans. Through testing, it can effectively compare and evaluate the sealing process and sealing performance of the package, provide scientific digital basis for determining the relevant production technical indicators, and can also perform the sealing performance test after the drop, pressure (combined with electronic universal tester) test. .
2, soft canned packaging pressure resistance, bursting performance test
The test indicator can be used to measure the pressure resistance of fruit soft cans and used as a control for crack resistance during turnover. Due to the ever-changing turnover conditions, it is necessary to carry out simulation tests according to various situations, such as maximum pressure resistance, constant pressure deformation measurement, constant deformation measurement pressure and other test items, in order to comprehensively analyze the pressure resistance performance of soft cans Problems caused by packaging damage during transportation or transit of the product.
3, soft canned packaging opening force (removal stripping force) test
Soft can packaging if the sealing strength is too large, it is inconvenient for consumers to open, especially a considerable part of the consumers of such products is a minor; but the opening force is too small, it is very easy to damage during transport, so must be open Appropriate control, the need to simulate open force test products, generally divided into 45 degrees, 90 degrees, 180 degrees opening force test.
4, cover film mechanical strength test
The mechanical strength of the cover film is also an important indicator. If the tensile strength is not good, it can easily break when opened. At the same time, because the cover film is the most thin film packaging part of the entire soft can package, its peel strength, puncture resistance performance and heat sealing performance all need to be controlled.
5, barrier performance test
The flavor and nutrition of fruit products are easily oxidized and deteriorated. Even if the taste of the fruit products varies with the date during the shelf life, in order to ensure its nutrition, flavor and quality, barrier materials must be used. Oxygen permeability and moisture permeability test.
