M'dziko losintha lazopaka, makamaka mupp woven bag industry.companies akutembenukira kuzinthu zophatikizika kuti apititse patsogolo chitetezo chazinthu ndi kukhazikika. Zosankha zodziwika bwino za pp woven valve matumba ndi mitundu itatu yophatikizika yophatikizika: PP+PE, PP+PE+OPP ndi PP+PE yokhala ndi pepala limodzi lokha. Mtundu uliwonse umagwira ntchito yapadera ndipo umakwaniritsa zosowa za mafakitale osiyanasiyana.

1. PP + PE (polypropylene ndi polyethylene): Kuphatikiza kumeneku kumagwiritsidwa ntchito kwambiri chifukwa chakuchita bwino kwambiri kwa chinyezi komanso kukhazikika. Chigawo cha PP chimapereka mphamvu ndi kugwetsa misozi, pamene gawo la PE limapereka kusinthasintha komanso kutsekedwa pamwamba. Mtundu uwu wa phukusi kwathumba la valve pansindi yabwino kwa zakudya, kuwonetsetsa kutsitsimuka ndikutalikitsa moyo wa alumali. Amagwiritsidwanso ntchito kwambiri pakuyika zinthu zogula, pomwe chitetezo kuzinthu zachilengedwe ndikofunikira.

2. PP+PE+OPP (Oriented Polypropylene): Kuphatikizika kwapamwamba kumeneku kumatengera mapindu a mtundu woyamba pang'onopang'ono powonjezera gawo la OPP lamatumba a valve pansi, zomwe zimathandizira kuwonekera komanso kusindikiza. Wosanjikiza wa OPP ali ndi mawonekedwe onyezimira ndipo ndi njira yowoneka bwino kwa ma brand omwe akufuna kupititsa patsogolo kukopa kwazinthu zawo. Mtundu uwu umatchuka kwambiri m'makampani opanga zakudya zopatsa thanzi komanso zokometsera, komwe mawonekedwe amathandizira kwambiri pakusankha kwa ogula.

3. PP+PE Single Ply Kraft Paper: Njira iyi ya eco-friendly yaad* chikwama cha nyenyeziamaphatikiza mphamvu ya polypropylene ndi polyethylene ndi kukopa kwachilengedwe kwa pepala la kraft. Kraft pepala wosanjikiza sikungowonjezera kukongola kwa rustic, komanso kumapangitsanso kukonzanso. Kupaka kwamtunduwu kukuchulukirachulukira m'gawo lazinthu zachilengedwe komanso zachilengedwe, pomwe kukhazikika ndikofunikira kwambiri kwa ogula.

Pomwe makampani akupitiliza kuyika patsogolo kukhazikika komanso kukhulupirika kwazinthu, mayankho ophatikizika awa azigwira ntchito yofunika kwambiri m'tsogolomu.
