Important index of blister packaging thermal bonding strength in milk tablet packaging

At present, "dry milk tablet" in the domestic market gradually become a hot trend, market sales, products in short supply, so that the enterprises have increased product research and development efforts. In contrast, the demand for blister packaging will continue to grow steadily." "Dry milk tablet" adopts bubble cover packaging form, with convenient consumption, easy to carry and other humanized characteristics, and bubble cover packaging has high barrier, the packaging of milk tablets between less interference, good health and other advantages, well catered to the psychology of consumers.

Among the performance indexes of blister packaging, thermal bonding strength is one of the most important, and its strength directly affects the quality of blister packaging. XLW (M) intelligent electronic tensile testing machine was used to test the thermal bonding strength of flat blister-cover packaging, and the principle, parameters and specific test process of the equipment were briefly described, so as to provide reference for the monitoring of the thermal bonding strength of blister-cover packaging in milk industry.

Milk tablet blister packaging, PVC film and PTP aluminum foil as packaging materials. In blister packaging, each milk tablet has little influence on each other, less interference, and the probability of contamination is reduced. In addition, blister packaging also has the characteristics of high barrier, good sealing, excellent health performance and so on. The demand for blister packaging by major dairy enterprises continues to grow. In order to ensure the air tightness and independence of the bubble cover packaging, it should ensure that the holding part has good thermal bonding strength, otherwise, when the milk sheet in one of the bubble eyes is taken away, the rest of the bubble eyes will be prone to air leakage, leakage, resulting in dry milk sheet moisture, deterioration, and even damage the phenomenon. Therefore, thermal bonding strength is an important factor affecting the quality of blister packaging.
