Additives
Additives are an important addition to paper as a
material
.
Without additives, we are left with materials in a less
enhanced
state.
CMC
CMC (
Carboxymethyl cellulose
) is an additive used to aid in the bonding of
fibres
.
Soda ash
is added to ensure that the strong bast fibres remain which occurs due to the non-cellulose parts being dissolved.
Scissors
Scissors offer a simple way of cutting
straight
and
curved
lines on thin card and paper.
Stanley knives
Stanley knives are used to allow for cutting of
boards
and some thin sheet materials.
Surgical scalpels
Surgical scalpels can cut very
precise
shapes but they are very
sharp
.
Circle cutters
Circle cutters offer a similar blade but can cut accurate circles using the
diameter
.
Perforation cutters
We can use
perforation
techniques to partially crease the paper or card using a perforation cutter.
Guillotines
and
paper trimmers
Lastly, guillotines and paper trimmers can cut
large sheets
of paper or card.
