No te hoê puohu raau aluminum foil, e itehia te huru maitai o te tao'a i roto i te puai o te tao'a. No reira, e rave rahi mau mea e haafifi nei i te puai o te mau pute aluminum no te mau raau, e ua riro te reira ei taviri no te haamaitai i te huru o te mau tauihaa.
1. Te mau materia no te haapiiraa e no te mau pŭpŭ tauturu
Te tapearaa matamua o te aluminium, o te tao'a tarai ïa o te tapo'i tapiri, e e mana rahi to to'na huru i ni'a i te puai o te tao'a.
On the one hand, E haaparuparu te mau tafetafeta o te mori arahu i nia i te aluminum foil matamua i te tapiri i rotopu i te tapiri e te apoo matamua o teuminum. If the surface of the original aluminum foil has oil stains and the surface tension is lower than 31×10-3μm, e mea fifi ia tapae i te faito maitai roa a'e. I te tahi a'e pae, the metal composition and insufficient surface brightness of the original aluminum foil affect the strength of the heat seal, and the quality of the original aluminum foil must be strictly controlled.
2. In terms of adhesives
Te tapiriraa, o te hoê ïa tao'a taa ê e tao'a faatahe to roto. Ua taamuhia te reira i ni'a i te vahi pouri (e aore râ, i te tahi atu pae) o te aluminum foil matamua i raro a'e i te tahi mau huru tupuraa, e mǎrô i roto i te hoê e'a mǎrô no te hamani i te hoê tapiri tapiri, which plays a decisive role in the heat seal strength of the product
I teie nei, most domestic manufacturers use imported raw materials to prepare adhesives, and the products can achieve higher heat sealing strength. Tera râ,, e mea moni rahi roa te moni hoo o te mau tauihaa e haponohia mai. Ia noaa mai te moni rahi no te mau tao'a, ua haamata te tahi mau taata hamani tauihaa aravihi i te pae no te maimiraa i te pae ite aivanaa i te rave i te mau maimiraa e i te hamani i te hoê â mau tauihaa i te fare.
3. Faanahoraa no te hamaniraa
I raro a'e i te hi'opoaraa a te tahi mau faanahoraa, e tuuhia te tapiri i nia i te hoho'a matamua o te aluminum no te hamani i te hoê hoho'a teata, and the quality of the finished composite film will directly affect the heat seal strength of the product. I rotopu i te mau faito faufaa roa ' ' e, te vai ra te vitiviti o te pereue, te anuvera o te e'a mǎrô, te hoho'a, Te mau nota, rahiraa o te mau reni, e te ti'araa e te vahi o te ohu o te pereue.
Na te vitiviti o te pereue e faataa i te taime mǎrôraa o te pereue i roto i te e'a mǎrô. Mai te peu e mea vitiviti roa te tere o te pereue e mea teitei roa te anuvera o te e'a mǎrô, the solvent on the surface of the coating film will evaporate too quickly, resulting in residual solvent in the film, e eita te hoho'a o te pereue e nava'i, e e mea fifi roa ia hamani i te hoê, tapo'i paari e te pautuutu maitai. Affect the heat seal strength of the product and cause adhesion between product layers.
Te huru o te anilox, Te mau nota, Na te numera o te mau reni e te ti'araa e te hoho'a o te tipi o te taote e faataa i te me'ume'u e te huru o te hoho'a o te pereue. Mai te mea e, e ere te ma'itiraa e aore râ, te faatanoraa i te mea tano, the adhesive will not be evenly coated on the surface of the original aluminum foil, Te mau mana'o tauturu no te haapiiraa, the heat sealing effect of the product will not be good, e e ite-atoa-hia i ni'a i te reira te puai.
4. Te anuvera i te pae no te taatiraa
Ua riro te anuvera no te ve'ave'a ei tumu faufaa rahi no te faaino i te puai o te ve'ave'a. Mai te peu e mea raro roa te anuvera, eita te tapo'i tapiri e nehenehe e tapiri-maitai-hia e te hoho'a PVC, e e ere te taairaa i rotopu i te tapiri e te hoho'a PVC i te mea puai. Mai te peu e mea teitei roa te anuvera, e fifi te raau. No reira, e mea pinepine te anuvera no te ve'ave'a i te topa i roto i te area 150°C e te 160°C.
5. Te mau mana'o tauturu no te tuatapaparaa e te haapiiraa
No te tapae i te faito maitai roa a'e o te taatiraa, e mea ti'a ia haamauhia te tahi mau faaheporaa. Mai te peu e aita i navai te faaheporaa, eita te tapiri-noa-raa o te tao'a e te hoho'a PVC e nehenehe e taamu-maitai-hia e e tapiri-maitai-hia, but also air bubbles can be left between the two, and a good heat-sealing effect cannot be achieved. No reira, the national standard stipulates that the heat sealing pressure is 0.2mPa.
6. Taime taatiraa
E riro atoa te taime ve'ave'a o te ve'ave'a i te faaino i te puai o te tao'a. I roto i te mau huru tupuraa matauhia, i raro a'e i te hoê â faito ve'ave'a e te ve'ave'a, e nehenehe te hoê taime roa e riro ei taime no te taatiraa, e na te reira e faariro i te tuhaa no te ve'ave'a ei mea papû a'e e te maitai roa, e e nehenehe e faatupu maitai a'e i te puai i titauhia. Tera râ,, the technological conditions of modern high-speed pharmaceutical packaging machines cannot provide a long time for heat sealing. Mai te mea e, e mea poto roa te taime no te taatiraa, eita e navai te veavea i rotopu i te tapo'i tapiri e te hoho'a PVC. No te reira tumu, te haapapû nei te ture a te fenua e, te taime no te tuatapaparaa i te mau papa'iraa mo'a o te 1.
