Solvent free lamination adhesive 1018A/1018B

Product description
Type of adhesive
1018A/1018B is one solvent free polyurethane adhesive for flexible package it is one kind of high performance, low viscosity adhesive

The scope of application:
1018A/1018B is a solvent-free adhesive soft packaging a high performance, not only is suitable for the ordinary transparent / aluminum composite structure, also used in high performance three layer composite structure. The adhesive has good mechanical properties and wet ability, boiling water resistance (100 degrees C 30-40 minutes)
1018A/1018B is suitable for various kinds of plastic / plastic, aluminum plating film such as BOPP, PET, PA and CPP, PE, VMPET, VMCPP etc. the structure of the composite, the aluminum foil and PVDC also showed good adhesion. Composite products with good final composite strength, heat sealing strength and heat resistance, the transparent structure can meet the requirements of pasteurization and boiled. Application of structural + typically include:
 BOPP (PET) / met.CPP (met. PET) / PE
 Nylon / PE (CPP)
 Nylon / PVDC / PE
 BOPP  (PET) / PE (CPP)
 PVDC / WPE
 PET / Al / PE

(film must haave corona treatment before lamination, to achieve appropriate surface tension) .

Data Specification

 
Food packaging regulations

1018A/1018B adhesive system in accordance with the provisions of the following articles:
The food and Drug Administration FDA CFR 27.175.105 USA
The plastic limit and migration characteristics of 2002/72/EC terms
Standard GB-9685-2005 with additives of food containers, packaging materials of China

How to use:

Processing technology

Applicable device:

Solvent free composite equipment with multi roller machine application system, equipped with automatic mixing device

Add:
use of hybrid element will be mixed into the coating adhesive for good
the gap of adhesive should be kept as small as possible.

Curing:

The curing process depends on the film, composite process and environmental conditions, in the 35 - 40 C temperature and relative humidity of 60% conditions, composite products for rewinding and slitting in curing for 12 hours -48 hours. Fully cured after the formation of transparent film, tasteless, elasticity, ageing resistance.

In the greenhouse and the relative humidity is 40% - 80%, the curing process as below

The typical structure and bonding properties
1018A/1018B is a solvent free adhesive soft packing for high performance, not only applicable to ordinary transparent / aluminum composite structure, also used in high performance three layer composite structure. The adhesive has good mechanical properties and wet ability, boiling water (100 degrees C, 30-40 minutes).

Operating temperature 30 - 45 degrees C (under normal conditions is set to 40 degrees C)
The feeding unit 35 - 38 degree C
transmission pipe: 35 - 38 degrees C
Measuring Roll 40 degree C
The applicator roll 40 degree C
Composite temperature 30 - 55 degrees C
The speed of the machine is 0 - 450 m / min
The use of time 30 - 40 minutes

Coating
According to different purposes and soft packing structure, coating weight in the

1 - 3 g / m2 changes to further adjust the printing film.

Complex conditions
The precise tension control can avoid the stratification, size and film rolls etc..

Wheel life
1018A/1018B mixed adhesive varied with time in 40 degrees C viscosity:
The initial viscosity: 1700 mPas
In 15 minutes: 2200 mPas
In 30 minutes: 3300 mPas
In 60 minutes: 7200 mPas

Cleaning
equipment stop more than 30 - 40 minutes, require the use of solvents such as coating unit of Ethyl acetate or plasticizer mixtures (please use clean Caution! Rules). After the end of the running equipment, must clean entirely.

Shelf life
1018A with strong moisture absorption, should be properly sealed in a container , so as to avoid the water into and store in a cool, avoid direct sunlight, stored separately and isocyanate. Storage temperature: 10 - 35 C, the storage period is 9 months.
