Cosmetics packaging strength testing

Strength testing including tensile strength, peel strength composite film packaging materials, heat sealing strength, tear strength, durable thorn strength index. Tensile strength refers to the material before the snap under maximum stress value. Through detection can effectively solve the selected packaging materials for the machine machinery strength is not enough, and in the packing damage and fracture caused by under the action of external force. Also called composite strength and peel strength is a measure of the composite membrane, the bonding strength between layer and layer if the adhesive strength is too low, is extremely easy in the packaging used in separation between coating and produce the problem such as leak. Heat sealing strength is testing the sealing strength, in the process of preservation of the product and shipping, once the heat sealing strength is too low, leads to heat sealing problems such as cracks, leakage of contents. Durable thorn performance is to evaluate packaging hard puncture resistance index. Center in the chemical industry technical requirements and the progress of science and technology as the guide, based on the resource integration, technology sharing, analysis, technical advice for the body, is committed to building the bridge with research. For the purpose of 'concentration, professional, dedicated, committed to research and application of docking, pushing the development of chemical industry. Families and the chemical analysis test center is committed to promote the development of chemical industry, welcome all my colleagues to come to negotiations and cooperation. Corresponding testing instrument information is as follows: 1, XLW series intelligent electronic tensile testing machine, film, composite membrane, such as adhesives, adhesive tape stripping, tensile test, thermal bonding strength test, tear professional performance test. The series has XLW XLW ( B） XLW ( M） XLW ( PC） XLW ( G） And other model products. 2、BLD— 200 s electronic stripping tester: film, composite film, adhesive, adhesive tape stripping, tensile test, thermal test; Standard 200 n ( 30 100 n, n, n) And micro computer communication interface. 3,HST - H3 heat sealing tester: film heat sealing strength test specimen preparation, pressure, temperature, and time is adjustable. Using single chip computer control, the intelligent operation; Temperature PID precision parts, ensure temperature precise and reliable. 4,RTD - R2 heat sealing gradiometer: a material such as plastic film, flexible packaging composite membrane preparation in 5 groups of independent sample temperature, heat sealing five groups of sample at a time, high efficiency.
