MATERIAL UNTUK PRINTING
( MATERIAL UTAMA )
•
Untuk proses cetak diperlukan material dengan
sifat - sifat :
- Mudah menyerap / menerima tinta
- Permukaan cukup halus dan rata
- Tahan terhadap perlakuan pada mesin cetak
•
Contoh material untuk printing :
Kertas, Cellophane, NY, PET, OPP
SIFAT PELINDUNG (BARRIER)
MATERIAL PLASTIK
Semua material, kecuali kaca dan metal, bisa dilalui (“permeable”) oleh
uap air, udara dan gas-gas lainnya
Karena metal foil tidak transparan dan kaca tidak flexible untuk “flexible
packaging” umumnya digunakan bahan plastik (polymer)
Pengaruh uap air dan oksigen terhadap makanan :
- Potato Chips
Uap air
melempem
Uap air
bau tengik
- Makanan berlemak
Uap air
- Kopi bubuk
berjamur
MEKANISME PERMEASI GAS
MELALUI FILM TIPIS
Tahap I
: Gas melarut dalam film
Tahap II
: Gas terdifusi melalui film
Tahap III
: Gas keluar dari film ke tempat
yang baru

MATERIAL UNTUK HEAT SEALING
Heat sealing adalah proses penyatuan (“welding”) 2 polymer termo
plastik dengan menggunakan panas dan tekanan
Ada dua macam bentuk material untuk heat sealing :
Film
: PE, LLDPE, CPP
Coating
: Acrylic, PVDC, NC
Cara heat seal ada 3 :
1. Conduction Sealing
2. Hot Wire Sealing (Impulse Sealing)
3. Dielectric Sealing

MATERIAL UNTUK PRINTING
( MATERIAL UTAMA )
•
Untuk proses cetak diperlukan material dengan
sifat - sifat :
- Mudah menyerap / menerima tinta
- Permukaan cukup halus dan rata
- Tahan terhadap perlakuan pada mesin cetak
•
Contoh material untuk printing :
Kertas, Cellophane, NY, PET, OPP
SIFAT PELINDUNG (BARRIER)
MATERIAL PLASTIK
Semua material, kecuali kaca dan metal, bisa dilalui (“permeable”) oleh
uap air, udara dan gas-gas lainnya
Karena metal foil tidak transparan dan kaca tidak flexible untuk “flexible
packaging” umumnya digunakan bahan plastik (polymer)
Pengaruh uap air dan oksigen terhadap makanan :
- Potato Chips
Uap air
melempem
Uap air
bau tengik
- Makanan berlemak
Uap air
- Kopi bubuk
berjamur
MEKANISME PERMEASI GAS
MELALUI FILM TIPIS
Tahap I
: Gas melarut dalam film
Tahap II
: Gas terdifusi melalui film
Tahap III
: Gas keluar dari film ke tempat
yang baru

MATERIAL UNTUK HEAT SEALING
Heat sealing adalah proses penyatuan (“welding”) 2 polymer termo
plastik dengan menggunakan panas dan tekanan
Ada dua macam bentuk material untuk heat sealing :
Film
: PE, LLDPE, CPP
Coating
: Acrylic, PVDC, NC
Cara heat seal ada 3 :
1. Conduction Sealing
2. Hot Wire Sealing (Impulse Sealing)
3. Dielectric Sealing
