Opening easiness of package, mainly designed for small packages, is a kind of packaging convenience characteristic offered to consumers. In the past, we focused on how to improve sealing performance and fastness of packages to avoid damage and leakage of the contents; while opening easiness of package was rarely mentioned and the real opening result of the packages was not good. Auxiliary tools like scissors had been often used in package opening, which would often lead to hurt to hands. This not only increased the difficulty of consumption, but also affected overall images of packages. The notion of opening easiness package has come to the market for a short period of time, and is warmly welcomed by customers. Therefore, opening easiness of package has become a tendency of package design.
How to improve opening easiness of package? Could perceptual knowledge of opening easiness be quantified into several testing items? This article will give the following introduction as to container and flexible package.
1 Container
Container package can be divided into bottle form and cup form. Bottle package, such as plastic bottle and glass bottle, is designed to be easily opened (usually by opening bottle cap) by consumers. The needed torque force in bottle cap opening should be controlled .To some caps with special anti-fake function; opening force of pull-tab should also be controlled. Cup package is mainly opened by peeling off the sealing place or by piercing the material of cup rim using tools like suction pipe. Therefore, for different packages, seal strength or puncture resistance of materials needs to be adjusted. For example, package of childrenĄ¯s beverage should be designed according to their grip strength and wrist strength. Generally speaking, the following parameters should be considered to improve opening easiness of package.
1.1 Friction Coefficient Testing
Friction coefficient of package external wall, bottle cap surface or cap material surface should be tested.
