Aluminum capstock is available both DC and CC material. Aluminum pp caps with light weight and easy remove. more details as below.
Introduction of Aluminum PP Caps
1, the mechanical / mechanical properties
No. Alloy Thickness (mm) Tensile strength and status Mpa Elongation% Yield Strength Mpa
1,8011 H18 0.20 ~ 0.30 220 ~ 260 ≥3 210 ~ 240
52,5182 H19 0.224 ≥380 ≥6 330 ~ 350
NOTE: uncoated plain aluminum after 205 ℃ / 20 minutes baking required more than the mechanical performance requirements.

Since the characters of PP caps, it has become more and more popular among in the aluminum industry.
Haomei Aluminium Closure Sheets are suitable for both transparent and non-transparent lacquering, and will not bend during curing process. For applications requiring deep drawing, such as long caps, Haomei aluminium closure sheets show very low earing, greatly reducing scrap rate for our clients.
Haomei Aluminum closure sheet is rolled to very fine tolerances to yield more closure per tonne of stock and to allow uninterrupted operation of high-speed, multiple-cavity presses. Its strength, high formability, low earring and printable surfaces make it ideal for pilfer-proof caps and vial seals.
