Yintoni umahluko phakathi kweengxowa zefilimu zefilimu / iibhokisi zesidlo sasemini kunye neemveliso zeplastiki zemveli?

Umahluko phakathi kweengxowa zefilimu zefilimu / iibhokisi zesidlo sasemini kunye neemveliso zeplastiki zemveli, kunye nokuphuculwa kokwazisa ngendalo, kunye neebhegi zefilimu ze biedegraham kunye neebhokisi zesidlo sasemini kutsala ngokuthe ngcembe abantu. Xa kuthelekiswa neemveliso zeplastiki zemveli,Iimveliso ze-biodegraphildYiba nomahluko omkhulu. This article will discuss the differences between biodegradable film bags/lunch boxes and traditional plastic products from three aspects: biodegradability, environmental protection and compostability.

I-1. I-biodegraphiance yomehluko obaluleke kakhulu phakathi kweengxowa zefilimu zefilimu / iibhokisi zesidlo sasemini kunye neemveliso zeplastiki zemveli ziyinto ye-biodegraphiance. Iimveliso zeplastiki zemveli zihlala zisebenzisa i-petroleum njengezinto eziluhlaza kwaye kunzima ukuphelisa. Iimveliso ezinobungozi ziveliswa kwizibonelelo zendalo ezihlaziyiweyo, ezinjengesitatshi, i-polylactic acid, njl njl. Iibhegi zefilimu ezinokudiliza / iibhokisi zesidlo sasemini zinokwanjiswa ziintsholongwane kwindalo esingqongileyo, ngaloo ndlela zinciphisa ungcoliseko lwendalo.

2. Umahluko khuselo lwefilimu yefilimu lefilimu / iibhokisi zesidlo sasemini zinegalelo elincinci kwindalo, ehluke kakhulu kwiimveliso zeplastiki zemveli. Inkqubo yemveliso yeemveliso zeplastiki zemveli ziya kukhupha inani elikhulu lekhabhoni, eza kuba nefuthe elithile kubushushu behlabathi. Ngokwahlukileyo, izixa ezincinci zekhabhoni ziveliswa ngexesha lokuveliswa kweemveliso ze-biodegraday. Ukusetyenziswa kweebhegi zefilimu zefilimu / iibhokisi zesidlo sasemini akuyi kubangela ungcoliseko olukhulu kwindalo kwaye kukhetho olunobuhlobo olunzulu.

3. Ulwalamano olusebenzayo lwenye into ebalulekileyo kwiibhegi zefilimu zefilimu / zebhokisi yesidlo sasemini kukungaqhelekanga. Iimveliso zeplastiki zemveli zinokuqina okuqinileyo kwaye azinakho ukonakaliswa zii-microorganisms kwindawo yendalo, ngoko ke azinakubhalwa ngokufanelekileyo. Ngokwahlukileyo, iibhegi zefilimu eziphilayo / iibhokisi zokutya zinokuchithwa ngokukhawuleza kwaye zigaywe zii-microorganisms kwaye ziguqulwe zibe sisichumisi esiphilayo ukubonelela ngezondlo emhlabeni. Oku kwenza ukuba iingxowa zefilimu zefilimu / iibhokisi zokutya inketho ezinzileyo enefuthe elincinci kwindalo esingqongileyo.

4. Umahluko osetyenziswayo kukho umahluko osetyenzisiweyo phakathiIibhegi zefilimu ezinokutsha / iibhokisi zesidlo saseminineemveliso zeplastiki zemveli. Iimveliso ze-biodegram zihlala zithambekele kwindawo enomswana, ukunciphisa ubomi beenkonzo zabo, ngoko ke kufuneka zigcinwe ngokufanelekileyo. Iimveliso zeplastiki zemveli zinezinto ezilungileyo zokutya kunye nezinto ezinamanzi kwaye zilungele ukusetyenziswa kwexesha elide. Xa ukhetha ukuba yeyiphi imveliso oza kuyisebenzisa, ukuqwalaselwa ngokubanzi kufuneka kwenziwe ngokusekwe kwiimfuno ezithile kunye neemeko zokusetyenziswa.

5. Umahluko kuphuhliso lwamashishini Imveliso kunye nentengiso yeengxowa zefilimu zefilimu / iibhokisi zesidlo sasemini zinamathuba amakhulu eshishini kunye nokubakho. Njengoko ukwanda kokusingqongileyo kwendalo esingqongileyo, ngakumbi kwaye uninzi lwabathengi banyula ukusebenzisa iimveliso ezinokufowuna. Oku kukhuthaze uphuhliso kunye nokwandiswa kwamashishini ahambelana nemizi-mveliso, ukudala amathuba engqesho kunye nezibonelelo zoqoqosho. Xa kuthelekiswa, ishishini lezezimzimba lemveli lijamelene noxinzelelo olukhulayo kwaye kufuneka liphuhliselwe ngokuthe ngcembe kwicala elinobuhlobo kwindalo esingqongileyo.

Ukuzama ukuphakama, kukho umahluko ocacileyo phakathi kweengxowa zefilimu zefilimu / iibhokisi zesidlo sasemini kunye neemveliso zeplastiki ngokweplastiki, ukukhusela okusingqongileyo kunye nokhuselo. Iimveliso ezinobungozi zinganeli nje nje yongcoliseko oluncinci kwindalo esingqongileyo, kodwa zinokuguqulwa zibe zizichumisi zezinto eziphilayo kwaye zibuyiselwe kumjikelo wendalo. Nangona kunjalo, kukho imida ethile ekusetyenzisweni kweemveliso ze-biodegraday. Ngokubanzi, ukhetho lweemveliso eziza kusetyenziswa kufuneka lwenziwe ngokusekwe ngokusekwe kwiimfuno zokwenyani kunye neemeko zokwazisiswa kokusingqongileyo, kunye nokwazisa okusingqongileyo kunye nophuhliso oluzinzileyo kufuneka zikhuthazwe.
