Paper Sizes

There is a standardised system of related sheet sizes, based on a series of two different sizes called A or B - all of the same proportions.

All sizes have the rectangular of 1:sqrt2 which is mathematically unique - no other size allows paper to be cut or folded in half and yet retain the same proportion.

It is also not neccessary to give dimensions of paper, as descriptions such as A4 or A3 are in universal use.

Envelope Sizes

There is a standardised system of relative envelope sizes based on the A series of paper sizes. Also available is a range of imprint size envelopes which are pre metric sizes.

**Types of Envelopes**

Symbol Index

	Laser Guaranteed Guaranteed for use in laser printers, subject to manufacturer's guidance on grammage and use.
	Laser Compatible Compatible for use in laser printers, subject to manufacturer's guidance on grammage and use.
	Strength/Durability/Water Resistance These symbols relate to our polypropylene synthetic sheet JPP. Where strength, durability and water resistance are important. JPP Synthetic is the product to use.
	Envelopes We stock a large selection of coordinated envelopes for that special job. Specialty envelopes are available in DL 110 x 220mm. Please call for other sizes or refer to specialty envelope section of price book.
	Watermarked Brand names, logos and other designs are imparted on the sheet by a dandy roll in the paper making process.
	Normal Inks Traditional offset inks may be used instead of quick drying oxidising inks.
	Australian Made Stocks that display this symbol are manufactured in Australia.
	Reels/Sheeting Papers displaying this symbol are available in reels for customised sheeting purposes.
	Acid Free No free acids are present due to care taken in the manufacturing of the pulp to eliminate any active acid. Only uses alkaline additives. Acid free papers are used for wrapping or storing jewellery, china, silver or photographs.
	Recycled Made up of recycled fibres which have been extracted from existing paper products to be used in the manufacture of further paper products. Recycled paper can be 100% recycled or consist of a mixture of pre and post consumer waste along with some virgin fibre to add strength.
		Pre-consumer Waste Only types of waste from the mill itself, such as offcuts or broke.
		Post Consumer Waste Paper has been used in some form after leaving the mill. Gathered as offcuts from paper merchants, office waste or printed waste through household recycling.
		Wood Free Free from wood based impurities such as Lignin found in the plant structure by a chemical pulp process. Leaving only pure cellulose, the ideal substance to make paper. Stops discoloration problems. Also an environmental issue as no bleaching is generally necessary once Lignin is removed.
	Environmental Accreditation A paper mill that has internationally recognised environmental standards and an ongoing commitment to the conservation of natural resources. The paper mill has established an environmental management system with standards in excess of legal requirements that operate in tandem with their product quality controls.
	Sustainable Forestry Practices Fibre used in the production of paper that shows this symbol is sourced from pulp suppliers who practice sustainable forestry techniques and/or managed renewable plantation forests.
	Totally Chlorine Free (TCF) No chlorine gases or compunds are used in the bleaching process.
	Elemental Chlorine Free (ECF) No chlorine gases are used in the bleaching process. The ECF process uses chlorine dioxide - when the bleaching process is complete, the chlorine atom leaves the process as chloride or salt. * There is no toxological difference between waste waters generated from ECF or TCF based bleaching.
	ISO 9706 Long Life Papers displaying this symbol are guaranteed by international standards to last up to 100 years.
