Adhesive for cardboard boxes packaging

[lukin1977]

Sorry if this is the wrong forum to post this thread but since it is a bonding application I am posting it here

We will be packing one of our product in cardboard boxes

Can anyone recommend an industrial adhesive for cardboard? My knowledge on this subject is scarce
Somebody told me the liquid silicone will do the work I need but I could no find any supplier near here yet
The adhesive must bond the cardboard fast since the boxes will be closed in the production line

Can you use hot melt adhesive?

You are judged not by what you know, but by what you can do.

Thanks

I am looking for something that can be apply manually by the operator
Hot melting adhesive is a good option but a little costly for our process

Why not use packing tape?

 

[lukin1977]

because management thinks is ugly. they want a box closed with some type of glue.

Tell them what hot melt costs, and see if the packing tape is still ugly?

You might be able to find a suitable spray adhesive (3M supper 77?) that won't have the initial investment of hot melt, but going through cans of that would be costly.

Sodium silicate adhesives are the cheapest you can find.

Box staples.

Hot melt is too expensive?

A good hand-held gun is maybe $20.
Glue sticks in bulk maybe 50 cents each for 10 inches.

If that't too expensive you need to consider flour and water.

MintJulep - for some boxes the $20 guns don't keep up. For industrial use, it's more like one of these

or

http://www.uline.com/Product/Detail...lue-Sticks/High-Performance-Glue-Gun-450-Watt

(will go through 9-11 pounds of glue per hour)

What is missing from the OP is any sense to the size of the boxes or the desired level of adhesion. What I think his boss is missing is that conventional tapes provide anti-snag properties by covering the exposed edges and corners of the flaps, though they offset that by being more difficult to open by grabbing a corner by hand and pulling.

Some makers have peel-and-stick flaps for a no-tape seal and no additional tools, such as

but I guess transfer tape could be applied to non-self-sealing cartons.

The OP is also concerned with suppliers 'near here' but gave no indication where 'here' is. Too many loose ends to be sure of a solution.

thanks for all your comments

We are reluctant to use the hot melt guns not only because of cost but also because we think that they will be broke in less than a week by the operators. You wont believe the things this guy can break. All has to be "monkey proof"

Box size is 300x300x100mm
Flaps to be glue are 2 opposite faces. Bottom and up face. 300x100mm each and they overlap entirely

Near here: We are in Paraguay

Level of Adhesion: Dont know how to grade the level of adhesion that we need. Once a box is closed it should remain closed until it is open by the consumer.

Great information! We use a lot of sodium silicate in our manufacture process. I will be doing some tests with it

"You wont believe the things this guy can break." Good reason not to let them near a stapler. Or if he has a stapler, near anyone else.
