Chemical Properties Causing Oxygen and Water
Sensitivity
Hygroscopy is one of the properties of elements
and molecules that causes water and oxygen
sensitivity. It is the characteristic of a
substance to draw and hold on to water molecules
from the atmosphere. It is important to note that
once the substance attracts moisture, it becomes
chemically altered. Substances exhibiting this
quality include ethanol, sugars, glycerol, salts,
chlorides, potassium and sodium hydroxides.
Presence of the smallest ration of these
substances in the product causes Hygroscopy and
must be avoided. Bulk bags liner are special
types of bags available in varying sizes used to
protect products from moisture contamination
during transportation.

Creation of Oxygen and Moisture Barriers in
Products Handling
This is done through various means but the most
common one is the use of liners. Introducing
liners inside the package ensures that the
product is excluded from the atmosphere. Caution
must be taken on the characteristics of the
material used especially when considering the
duration or the shelf life of the product. The
effect of regular temperature changes during
transportation and storage must also be
considered while choosing an appropriate
protective material.

Strength and Firmness Properties That Ensure
Greater Protection
The ability of a material to withstand pressure,
temperature fluctuations and even mechanical
stresses greatly contributes to the firmness and
protection from environmental influences.
Development of cracks and micro pores are some of
the weaknesses that can go undetected and lead to
damage of the products. Thorough analysis of
available materials must be done as per the
protection requirements for material firmness.
5
Chemical Composition of Protecting Material
The chemical composition of the liners largely
depends on the product characteristics such as
Hygroscopy or dust producing properties.
Polythene liners or EVOH liners are commonly used
and the actual polymers combined depend on the
manufacturer.

Commonly Available Dimensions
The average or the typical height of the bulk bag
ranges from 30 up to 70 inches and base seam
dimensions of 35 41 inches. The particular
dimensions are however nothing to worry about so
much because custom-made bags are available.
However, when there is an element of staking or
the bag being self-supporting, the base size
should be as large as possible due to stability
of the flexible packaging material.

Recommended waste management practice after use
handling
Recycling of used material is the best waste
management system. In case the material is not
recyclable, incineration can be done to avoid
littering and environmental degradation. It is
important to consult with individual states
regulations for clear direction on best disposal
practice.
