Milk Film Production Process

Milk film

(1), production process:

mixing ---- blowing film ---- printing ---- maturing ---- cutting packaging.

Blowing film: strictly according to the formula production, focusing on the control of thickness, such as physical indicators.

Printing: color and signature, ink resistance and ink adhesion.

Slitting: specifications, volume direction and volume weight.

(2), the use of technology: all milk films are heat sealing, side sealing and back sealing.

① high temperature milk film: hot filling -- 121℃30 minutes sterilization -- inspection packaging placement -- delivery.

Sterilization type:

water sterilization:

The water in the sterilization pot buried all the products, the steam heated the water to 121℃, the hot water heated the product sterilization, hot water circulation. Features: uniform temperature, small temperature difference in the pot, thorough sterilization. The product in the pot is semi-suspended.

Steam sterilization:

The steam heats the air and the hot air heats the product to 121 ° C.

Features: The temperature in the pot is not uniform, the temperature difference is large, and the products in the pot are basically static.

② Medium temperature milk film: hot filling ————100℃ for 30 minutes sterilization ---- inspection package.

③ Baili coating: normal temperature filling hydrogen peroxide sterilization - ---- inspection packaging

④, ordinary milky film:

I, cold filling ----60℃ 8 hours fermentation ---- inspection packaging

II, cold filling -- inspection packaging -- cold chain transport
