About Paper Tubes
Paper tubes and paper caps are made from a variety
of paper Products, such as fiberboard, composite materials, paperboard
and Kraft paper. They have numerous applications, including telescopic
cans, lab and medical containers, donation cans, rocket bodies, coin
banks, pencil caddies, shipping and cores for winding various goods.
Products requiring paper cores could be anything from paper towels to
carpet rolls to wrapping paper and packaging tape. Paper tubes may be
seamed or require an end cap. They are often labeled, either with a colorful
wrap or printed right on the tube. Paper tubes do not necessarily have
to be cylindrical; they can be square, rectangular, triangular or cone-shaped.
When choosing paper tubes or paper caps for a specific application, it
is important to consider the diameter, thickness of the walls, length,
liner, labeling requirements (i.e. color) and type of end closure. Typical
sizes for diameters run from 1.25” to 12”, but can be as
small as .317” or as large as 2’. Paper tube manufacturers
produce thicknesses ranging from .025” to 1”. Length varies
greatly, as well, from as small as .25” to 45’ or more; just
remember to factor in length needed for an end cap that fits inside.
Some paper tube manufacturers offer printed liners, water or rust resistant
liners, wax, poly, silicone and glassine liners and release papers. End
closures include pinched end/self-sealing, seamed-on tin, paper cuff,
self-locking metal end, plastic cap, paper caps, screw top, shaker top,
curled, disc and 2- or 3- piece telescopic-type closures.
Paper tube manufacturers can have different insulation materials available,
especially for spiral wound tubing. Vulcanized fiber (fish paper) is
a cotton rag base paper that is highly abrasion resistant, can withstand
temperatures up to 2211/4F/1051/4C and offers superior tear resistance,
bonding surface and electrical insulation. Electrical grade Kraft paper
can withstand temperatures up to 1941/4F/901/4C and offers excellent
dielectric strength. Phenolic Kraft paper exhibits electrical properties
and excellent structural integrity. Kraft can be combined with other
foils, decorative colors, plastic films or other substances with no difficulty
in order to fulfill application specifications.
Paper tubes offer many benefits, as opposed to other types of materials.
Paper does not promote condensation on parts. It’s tough, yet flexible.
Paper is made from a renewable, recyclable resource and, therefore, is
environmentally friendly. It offers great mechanical protection. It can
also handle high temperatures, up to 4001/4F/2001/4C. Most importantly,
paper is inexpensive.

Types of Paper Tubes
- are any
tubes made from spiral wound cardboard material. They serve
many purposes from cores for various products to storage containers
and shipping purposes.
- is a small paper tube used to hold specific monetary amounts of coins of the same denomination.
- are tubes made from composite paperboard, which
is a layer of fluted material sandwiched between two layers of linerboard.
- are tubes made from fiberboard
and can be used for individual roll storage, to protect sensitive
fabrics from crushing, to separate
secure small lots, to provide a location for return goods and to make “bottom” rolls
accessible when an entire roll is not cut.
- are cardboard tubes that paper products are rolled up into for compact shipping that does not bend or crease the material being shipped.
- ,
also called mailing tubes, are tubes, potentially having graphic advertisements
printed on them, which are used for the express
purpose of shipping items that fit conveniently in a tube. End cap
materials include wood, metal or paper.
- is a large, water-resistant cylinder paper form used in concrete pouring applications.
- are tubes
that are typically spiral wound and used for any material that requires
a center, including such things as paper
towels, fax paper rolls, tape and film products.
- are
composite containers typically made from paperboard material with an
inner liner that provides a
protective barrier. Thicknesses
and sizes vary, as do types of closures and label options.
- have
longer cores.
