SUITABILITY OF STOCK AND GRAIN
Minimum stock weight as a general rule is 250gsm art or 200gsm one-sided board. Maximum stock weights vary according to specific job designs. Please contact us directly for more information. Surfaces for gluing need to be compatible with the water-based adhesive we use. If you are in doubt please check with us, as we can run tests to establish if the surfaces is glueable. For best results a glue flap width of 20mm is required, (15mm minimum). Grain directions are shown on individual drawings under CARTON SPECIFICATIONS.
We run many designs that are not shown in the specification sheets, (there are far too many unique designs to list). Please do not hesitate to speak to us for ideas; it is quite likely we have done what you require, or something similar before.
As a general rule, coatings that are NOT glueable are: Gloss UV coating, machine varnish, normal gloss & matt cello – polypropylene and some inks. Please use a glueable gloss cello with any item to be cold glued with gloss cello, or in case of matt cello use scuff resistant matt cello. We cannot cold glue cello to cello (even glueable cello as the water based adhesive will never dry). We have facilities to glue cello to cello folders using hot melt adhesive, subject to design. Wherever gloss UV coating is used it must be a glueable gloss UV. ALWAYS remove ink from under the UV coating on glued areas. Wherever aqueous coating is used, ALWAYS remove ink from under the aqueous coating on glued areas. It is preferable to strip coating from glued areas on all jobs, and just bleed the coating 3mm to 4mm onto the glue flap. Matt cello always marks a little. These marks show more easily when solid dark colors are used. It is possible to glue the pocket with minimal marking, but when folding to finished size it is likely that you will see a polishing mark on the back cover. Depending on the severity of the marking, the folder may not be able to be folded to finished size. There is a scuff resistant matt cello that minimizes the risk of marking. Please contact us directly for more information.
JOBS FOR DIE CUTTING
We can arrange the manufacture of the knives, stripping units (male/female), counters etc; we will also store for up to 3 years at no charge. Flatbed jobs: grip edge MUST be flush to the edge of the pallet and sheets must be supplied front to view (face/outside Up). If the job is not supplied correctly, it may be returned to be amended before production can commence. Grip and lay edges MUST BE MARKED on all skids.
SHEET SIZE CAPACITIES
Cylinder Min: 210mm x 280mm
Max: 570mm x 820mm
Flat Bed Min: 360mm x 400mm
Max: 750mm x 1050mm
Crash Lock Cartons PLEASE NOTE: the print side, relative to the position of the side, and base glue flaps is important. Please contact us for further advice and information if you are in doubt.
Folders that cannot be folded to finished size in one pass can often be folded complete with a second pass through the machine. Over trim, opposite the pocket on single pocket folders, is to be less than 6mm.
There are many varieties of wallets, envelopes and photo frames. Please contact us directly for more information.
Glue flaps must be 20mm, and on the body of job, NOT ON THE POCKET FLAP. Stock must be minimum 250gsm Hi Bulk or 1 Sided Board; other stocks may not form properly. Grain direction is CRITICAL and MUST run at a right angle to the glue flap. Good creasing is essential, if you cannot hand fold easily our machine may not be able to run the job. Pocket must be minimum 65mm deep to a maximum of 150mm. Gusset sizes available are 5, 6, 7, 8, 9 & 10mm. For other sizes please ask. We prefer to do the die cutting of gusseted folders and wallets to ensure the creasing is suitable for our capacity folding/gluing machines.
When requesting a quotation please supply a detailed drawing with dimensions.
We can mechanical apply window film to cartons or custom die cut pick and place window applications. We carry a range of different thicknesses in PVC, PET and Acetate all of which are Food Grade Certified. We ask for 15mm panels surrounding the window patch to allow for glue spread. If you are unsure what material would be best to window the carton, we are happy to advise.
GENERAL NOTES ON MARKING
Carton gluers are belt driven and not gripped as in the case of printing presses ans die cutting equipment, therefore the stock weight is important. Once again there are variations to the rule, generally speaking 220gsm Art Board would be the minimum stock weight for our gluing machines. Another important point is that printed jobs go through a gluer should be varnished or coated (excluding glue areas) to protect the print from smudging or scuffing, especially in the case of slow drying inks.
We have inline taping equipment for:
Standard double-sided tape applications. E.g. wobblers, shelf talkers & mailers
Peal and seal tape applications for Document Wallets etc...
RF SECURITY TAGS
We have equipment for the placement of RF security tags on the inside of cartons.
TIPPING ON FACILITY
We have machinery to tip cards (amongst other things) on to advertising brochures or the inside of cartons etc...
Peelable glue, also known as removable glue, or gummy glue is ideal for direct mail applications. It is designed to hold two panels together until it gets to the end user. This makes it a suitable closure for self-mailers and brochures. Peelable glue can be removed without tearing paper fibres, and can be easily rubbed away. Peelable glue is applied as a hot melt. It is neat and attains strength in seconds, making it a good choice for applications that require glue to be placed in a visible location.
Stock weights from 200gsm to 350gsm
Roll fold only 2, 3 or 4 panels
Stock must be coated to prevent fibre tears when opening, e.g., celloglazed, UV coated or varnished
JOBS SUPPLIED FOR GLUING ONLY (PREVIOUSLY CUT AND CREASED)
For jobs supplied cut and creased for machine gluing, the creases must fold square and must snap into the crease when folded by hand, otherwise the machine cannot effectively fold on the crease. This is typically problematic with thinner stock weights. All holes to be stripped out or nicked securely in position including struts etc. With crash lock cartons, please use a CUT CREASE RULE on a 45-degree angle for the glue flaps on the base. Please contact us directly for more information.
ALL CREASES MUST BE BOLSTERED
