Puke Meaʻai Paʻa

I kēia manawa, hiki ke hoʻokaʻawale ʻia nā ʻeke ʻeke meaʻai maloʻo ma ka mākeke i loko o nā ʻeke ʻeke ʻeke hoʻokahi, nā ʻeke hoʻopili composite, a me nā ʻeke ʻeke hoʻopihapiha hoʻohuihui nui. Hoʻohana nui ʻia ka plastic plastic composite i loko o nā ʻeke ʻeke meaʻai maloʻo, a ʻo kēia ʻano ʻeke ʻeke meaʻai maloʻo he nui nā hui pū ʻana i ke ʻano mea.

Wahi a ka mea, aia kekahi mau ʻano i hiki ke hoʻohana ʻia no ka hoʻopili meaʻai hau. Hoʻokahi, PET/PE. ʻOi aku ka maʻamau o kēia ʻano mea i loko o ka ʻeke o nā huahana meaʻai wikiwiki. Loaʻa iā ia ke kūpaʻa maʻamau, ke kū anuanu, a me ka hana hoʻopaʻa haʻahaʻa wela haʻahaʻa, a ʻoi aku ka haʻahaʻa o ke kumu kūʻai.

ʻO ka lua, ʻo BOPP/PE a me BOPP/CPP. ʻO nā ʻeke ʻeke meaʻai maloʻo o kēia mau hale ʻelua he kūpaʻa maikaʻi loa a me ke kū anuanu, kiʻekiʻe haʻahaʻa haʻahaʻa wela-sealing ikaika tensile, a me ka hoʻokele waiwai. Pono e haʻi ʻia ʻoi aku ka maikaʻi o ka mea BOPP/PE ma mua o PET/PE, maikaʻi ia no ka kūʻai ʻana i nā huahana.

ʻEkolu, PET/VMPET/CPE, BOPP/VMPET/CPE. Ke hoʻohālikelike ʻia me nā ʻeke hoʻopihapiha hoʻokahi a me nā ʻāpana ʻelua, ʻoi aku ka paʻa a paʻa ka ʻano ʻekolu-layer, a he hana pale kiʻekiʻe. Eia kekahi, ʻoi aku ka maikaʻi o ka noho ʻana o ka papa aluminized i ka hana paʻi. Eia nō naʻe, ke hoʻohālikelike ʻia me nā mea i luna, haʻahaʻa haʻahaʻa wela Poor sealing hana a me ke kumukūʻai kiʻekiʻe.

ʻEhā, PA/PE, PET/PA/LLDPE, PET/PA/AL/PE, PA/PE. ʻO ke ʻano o kēia mau ʻano mea ʻehā i ʻoi aku ke kūpaʻa i ka maloʻo a me ka hopena, a ʻo ka papa PA e hōʻoia i ka pale ʻana i ka puncture maikaʻi. ʻO ka hemahema ʻo ia ke kiʻekiʻe o ke kumukūʻai hana, a hoʻohana maʻamau ia no ka angular a kaumaha paha nā huahana meaʻai.
