2. Analysis of the Seal-ability of the Most Common Milk Powder

2.1 Two-layers Sealed Cans

Cans Material: metal cans
Sealing Form: Two layer seals. Outer plastic cover + inner layer (tin foil or hard discus)
Representative Products: Wyeth milk powder (inner hard discus), Karicare (inner layer of tin foil film)

Inner sealing are completely sealed, while the hard discus is better than the tin foil film sealing, especially in transit, anti-extrusion performance is also better. Because, the tin foil film sealing protection of the inner seal can be said to be “disposable”, the product after opening, that is discarded, leaving only the outer plastic cover.

The outer plastic cover is the final line of defense for such packaging. So in the purchase, in addition to see the inner seal is complete, upside down shake, to see if there is the phenomenon of leakage powder; the same time, there is testing the outer plastic lid tightness how.

The middle layer of the discus of the compression resistance than the inner layer of tin foil stronger, seals the fresh performance than the outer plastic cover. So this three-tier seal design allows milk powder in the transport, the sale process has the best seal, preservation effect; After opening sealing, but also continue to play a sealed shelf life of the best results.

Three-sealed cans sealing is good, but the operation is one of the major drawbacks of inconvenience. Experienced mothers estimated the impact is very profound, discus very tight cover; opening sealing difficult, even with the tools forced open.
