What is BOPP tape and what is it used for?
BOPP stands for biaxially oriented polypropylene. The film is stretched in two directions during manufacture, which aligns the polymer and makes the finished backing far stronger and more dimensionally stable than unoriented film of the same thickness. Coated with a pressure-sensitive adhesive, it becomes the standard carton sealing tape used across packing halls everywhere.
LKJ® BOPP Packaging Tape is suitable for carton box sealing and stationery use, with a total thickness of 38 to 40 microns. It comes in light, medium and heavy-duty grades, so a light carton of empty cartons and a heavy export box do not have to use the same tape.
It is the general-purpose end of the LKJ® specialty tapes range: once a carton needs more than a plain seal, the job moves to a purpose-built grade. If you are not sure which grade that is, choosing a specialty tape by the job routes you from the job on the bench to the right family.
Where a box is overfilled, heavy, or needs a tamper-evident paper seal, a kraft paper tape is often the better answer because it forms a permanent bond that has to be ripped to open. The group makes those too, see the Prateek® Tapes kraft paper tape range for the biodegradable and recyclable option.
How many colours can BOPP tape be printed in?
Company logos and messages can be printed in up to 5 colours. Options for reverse printing and half-tone effects are available, which means a logo with shading or a gradient can be reproduced rather than reduced to flat blocks.
Printed tape is an efficient carrier for general advertising: every carton that leaves the plant travels with the brand on it. Standard message tapes are also stocked, with options including "Handle with Care", "For Export", "OK TESTED", "Fine Quality PVC Pipes" and more, and branding tapes are available for customised requirements.
If you want colour without print, the tape is produced in transparent, brown, milky white, red, green, blue and black, plus custom colours. Many plants use the colour itself as the code, one colour per shift, per line or per destination, so that a mis-sorted carton is visible from across the floor.
Which BOPP tape length should I order for a taping machine?
Hand dispensers normally run short rolls, and the tape is available from 50m upward for that. Automatic carton sealing machines are different: every roll change stops the line, so longer rolls mean fewer stoppages. LKJ® BOPP Packaging Tape is made in long-roll lengths of 650m and 1000m specifically for automatic dispensing machines.
Widths run from 12mm to 96mm as standard, with custom widths on request. Narrow widths suit stationery and light bundling; 48mm and above are the usual carton sealing sizes; the wider widths are used where a single strip has to cover a seam and the flap edges together.
Lalit Jain Industries has been making packaging and industrial tapes since 1987 from two units in Delhi NCR, and is ISO 9001:2015 certified. The wider group packaging range, including printed BOPP, is listed on Prateek® Tapes BOPP packaging tapes.
