Hard Pulp -
Chemical pulp with a high lignin content.
Handmade
- the original manner in which all paper was made. So
called from the fact that the sheet is formed by a workman
dipping a mould into the pulp vat and taking up sufficient
'stuff' to form a sheet of paper of the required substances.
A peculiar movement is required to felt the fibres together,
and this is only acquired after long practice and experience.
Headbox
- a tank supplying papermaking stock under a controlled
pressure.
Heatseal Paper
- body paper coated with an adhesive material that is
activated by the application of heat. The grade is used
mainly in the production of labels where products from
paper to metal will adhere.
Hold-Out
- resistance of a paper to ink absorption.
