Dị ka ihe atụ, mmiri permeability nke 12 um polyester metalized okpomọkụ lamination film (VMPET) bụ n'etiti 0.3g /㎡ · 24h ~ 0.6g /㎡ · 24h (okpomọkụ 30 ℃, ikwu iru mmiri 90%); The mmiri permeability nke CPP aluminized film (VMCPP) na a ọkpụrụkpụ nke 25 um bụ n'etiti 1.0g /㎡ · 24h na 1.5g /㎡ · 24h (okpomọkụ 30 ℃, ikwu iru mmiri 90%).
7.Oxygen permeability
Oxygen permeability na-anọchi anya ọnụọgụ oxygen penetration nke aluminum thermal lamination film n'okpuru ụfọdụ ọnọdụ, nke na-egosipụta size nke mgbochi nke metalized thermal lamination film na oxygen, dị ka oxygen permeability nke polyester aluminum pre mkpuchi film na a ọkpụrụkpụ. nke 25 um bụ banyere 1.24 ml /㎡ · 24h (okpomọkụ 23 ℃, ikwu iru mmiri bụ 90%).
8.The size nke elu esemokwu
Iji mee ka ink na nchikota ihe mejupụtara nwere ezigbo wettability na adhesion n'elu ihe nkiri ihe nkiri aluminom, a na-achọ ka esemokwu dị n'elu nke ihe nkiri ahụ dị n'ihu nke metalized kwesịrị iru ọkọlọtọ, ma ọ bụghị ya, ọ ga-emetụta adhesion na nchikota nke ink na nrapado n'elu, si otú a na-emetụta àgwà nke ihe a na-ebipụta na ngwaahịa ndị mejupụtara. Dịka ọmụmaatụ, esemokwu elu nke polyesteraluminum thermal lamination film(VMPET) chọrọ iru ihe karịrị dynes 45, opekata mpe 42 dynes.
