1. Moisture Barrier: Data te hi a awm a

1.1 Barrier hnathawh dan tehkhin dan

Test data tihchhuah tawhte hian moisture barrier zawhna chhanna chiang tak a pe a ni. PET leh oriented polypropylene (OPP) film thickness inang tehkhin independent testing atanga a lan dan chuan BOPP hian water vapor barrier performance a sang zawk hle a ni :

Bungrua	Tui hnim hring chhuahna rate (WVTR)	Oxygen inthlak danglamna rate (OTR) 1.1.
PET Film siam a ni	18.07 g/(m²·24h) a ni.	A rilru a buai em em a, a rilru a hah em em bawk a. 28.01 cm³/(m²·24h·0.1MPa)
BOPP Film a ni	3.36 g/(m²·24h) a ni.	651.60 cm³/(m²·24h·0.1MPa) a ni.

Data atanga a lan dan chuan BOPP hian water vapor transmission rate hi PET aiin a let 5.4 velin a hniam zawk a, hei hian moisture barrier performance tha zawk a lantir chiang hle. Industry source-te chuan oriented polypropylene-a moisture barrier hi PET’s aiin a let 3 velin a tha zawk tih an nemnghet . Water vapor barrier property danglamna hi polymer molecular polarity inang lo vang a ni .

1.2 PP hian Moisture Barrier a neih tha zawk chhan

PET nena khaikhin chuan PP-a moisture barrier sang zawk hi polymer chemistry nen a inzawm a ni. PP hi non-polar hydrocarbon polymer a ni a, tui molecule nena affinity hniam tak a nei a, chu chuan moisture permeability a ti hniam zawk a ni. PET hian ester group polarity sang zawk a nei a, chu chuan tui molecule te polymer structure kal tlang theihna tur interaction site tam zawk a siam a ni .

Packaging science literature atanga a lan dan chuan PP ang polyolefins te hi hydrophobic nature leh water molecule diffusion atana free volume hniam zawk avangin PET ang polyesters te aiin water vapor barrier performance hi a pianphungah a tha zawk a ni.

2.1 Oxygen Barrier: PET chakna

PP hian moisture barrier angin a tha zawk laiin, PET hian a thatna danglam tak a pe a, chu chu oxygen barrier tha zawk a ni. Test data ang chiah hian PET-a oxygen transmission rate chu BOPP’s aiin a let 23 velin a hniam zawk tih a tarlang bawk . Hei hian PET hi oxygen lut tur ngaihtuah berna hmuna hmanna atana duhthlanna duh ber a siam a—chu chu ei tur packaging-a shelf life rei tak mamawh ang chi te hi a ni.

Moisture barrier atan PET aiin PP hi a tha zawk em? Data hian a nemnghet: a ni, PP hian moisture barrier performance tha zawk a pe a ni. BOPP film-a water vapor transmission rate hi PET aiin a let 5.4 velin a hniam zawk a, hei vang hian PP hi moisture protection mamawhna application-ah chuan hnehtu chiang tak a ni. Mahse, barrier picture hi a nuanced zawk: PET hi oxygen barrier angin a tha zawk a, PP aiin a performance chu a let 23 velin a tha zawk.

Strapping application atan chuan moisture barrier hi a tlangpuiin primary selection criterion a ni lo va, mahse PP-a inherent moisture resistance—a non-polar hydrocarbon structure avanga lo awm—chuan pawn lama dahna, agricultural, leh humid-environment application atan a tha hle. PP leh PET strap i thlan dawnin hman dan tur kimchang ngaihtuah la: moisture exposure, load weight, leh oxygen barrier te pawh ngaihtuah tur a ni em tih te.
