Why is my packing tape not sticking?
The tape won't adhere properly because it cannot form a strong bond with the surface. In the same way, when you try to seal a box with tape, there may be factors that prevent the tape from sticking, such as a dirty or dusty box, improper tension in the tape gun, or adverse weather conditions.
Clean the Surface
Tape works best when the surface area is clean, meaning 100% free of dirt, oil, and debris. You want to eliminate anything that can get between the surface and the tape in order to create direct contact with the adhesive.
- Check for Moisture. Moist or humid air might be the cause. ...
- Clean. Wash the surface completely with water, using a rag and bucket.
- Dry. Allow plenty of time for the surface to dry, or use a fan or hair dryer.
- Tape. Now that your surface is clean and dry, the tape should stick properly.
The main component of the adhesive itself is always a polymer. Styrenic block copolymers, for example, are often used for adhesives on packaging and double-sided tapes.
If it hasn't set or bonded to the surface then potentially it might have broken down. Lack of bonding is usually associated with contaminates on the surface, any moisture at the time of application, not following the instructions or not removing any old sealant prior to applying it around a bath.
In the majority of situations, a good scrub with a 50:50 mixture of isopropyl alcohol (IPA) and water will do the job. The alcohol will dissolve light grease and water will get rid of dirt and accumulated dust. Make sure the surface is thoroughly dry before applying the adhesive tape.
Dirty Surface
Traces of dust, dirt, grease, and even the slightest hint of moisture before bonding will contaminate the adhesive surface and act as a barrier between the two. To prevent tape failure, prepare the surface, give it a quick wash with rubbing alcohol and dry it with a clean cloth.
The adhesives used in tape work differently. They're called pressure-sensitive adhesives (PSA) and include materials like silicones, acrylics and rubbers -- all polymers to which a tacky resin is added to increase stickiness [source: ThomasNet]. These PSAs rely on physical reactions, not chemical ones, to adhere.
Water disrupts adhesion by forming layers on polar surfaces that inhibit contact between the surface and the adhesive.
The strength of any tape depends on the tape's ability to resist the pull between the bonding items or surfaces. In a typical tape, the adhesives are made of substances that contain both positively and negatively charged molecules.
Is brown or clear packing tape better?
Brown packing tape is useful because of its strong adhesion and colour (matches or blends nicely with the cardboard box). On the other hand, clear packing tape also provides enough adhesion, but it doesn't block or cover the view of the box itself (visually unobtrusive). Still, brown tape is more common.
Shipping tape, sometimes called strapping tape, is like packing tape, only it's much stronger, both in terms of its makeup and adhesion.
Higher or lower temperature
Basically, tape or other forms of adhesion, will stick much, much better. Higher temperatures will make adhesive too soft and almost useless. On the other hand, lower temperatures will maintain the adhesive too hard to connect to another surface, so tape won't stick!
While the precise shelf life of your custom packing tape varies depending on the adhesive and the storage and handling conditions at your facility, most pressure-sensitive adhesive (PSA) tapes last approximately 12 months in the ideal environment.
Paper tape cannot bond with non-paper material so if you are sealing plastic bins, for example, then plastic tape is your best bet.
Alcohol to the rescue.
When you apply rubbing alcohol, the adhesive residue will lose its adhesion and will precipitate. This can also work with acetone, or nail polish remover. Keep in mind that alcohol or acetone may damage painted surfaces, so be careful when using these substances.
Rubbing alcohol is an effective solvent that's safe for use on many surfaces. Pour some of the solution on a clean rag or paper towel and use it to rub the residue until it comes off. For stubborn residue that refuses to budge, place an alcohol-soaked rag over the sticky area for a few minutes to soften it.
To remove adhesive residue from metal, you should try using rubbing alcohol, or isopropyl, first. Apply with a cotton ball and let it soak in. Most adhesives will break down on contact, and rubbing alcohol won't damage metal surfaces. If that doesn't work, baby oil is another useful alternative.
Applying a little bit of heat can help restore the adhesive of your stickers, allowing you to re-stick them to any surface. It's especially effective if the area is exposed to cold temperatures.
Gorilla Tape does not work on materials with high oil or plasticizer content, such as EPDM rubber or PVC. An acrylic tape, such as Crystal Clear Gorilla Tape, may be better suited for these materials.
Which is stronger tape or glue?
Glue offers higher structural strength and a long-term bond, which can protect boxed heavy products better. Tape offers completely sealed flaps though, better protecting the products inside the box from the environment.
Another example of a non-adhesive tape is a polytetrafluoroethylene PTFE thread-sealing tape or known as plumber's tape. The film is used in sealing pipe threads. This non-adhesive tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads.
3M VHB tape offers one of the strongest bonds out of any adhesive. In fact, VHB tape has been certified in the industry to have a powerful bond (it's in the name: VHB = “Very High Bond”). Its adhesive properties alone give it an incredibly durable hold on any surface.
The Adhesive
The name of the world's strongest adhesive is DELO MONOPOX. This is a modified version of the high-temperature-resistant DELO MONOPOX HT2860. This epoxy resin forms a very dense network during heat curing.
Yet when cold temperatures occur, the liquid component of the adhesive tape hardens, similar to what happens to butter in the refrigerator. The tape loses its natural form and its overall tackiness. It can therefore no longer make the adequate contact needed for good adhesion.
In cold weather conditions, the liquid component hardens and so the sticky tape not only loses the tack it has but also its natural form, resulting in the tape being unable to make the required contact needed to achieve the strong level of adhesion that is expected.
Water is usually not considered a “glue.” It tends to attenuate intermolecular forces and prevents close contact between two solid bodies (1). Hydrophilic surfaces are separated by several monolayers of water (~1 nm) (2, 3), well beyond the typical range of van der Waals interactions (<0.6 nm) (1).
Strongest tape for heavy-duty use: PVC tape
It's ideal for heavier duty applications, such as heavy shipments with large parts or bulky supplies. PVC is a premium quality tape available in two strengths based on your package weight: Standard strength: 2.2 mil thickness for boxes up to 40 lbs.
1.9 mil thick tapes are lighter weight and appropriate for sealing boxes up to 30 lbs. 2.5 mil thick is a heavy-duty tape that can handle sturdier packages – appropriate for sealing boxes up to 50 lbs. 2.9 mil thickness works as an extra heavy-duty sealer.
The search is over with Scotch® Sure Start Packaging Tape. This tough, strong tape comes off the roll easily and smoothly with no slivering or splitting, so you can skip the frustration and get to taping faster.
Can I use duck tape for packing?
Duct tape generally doesn't adhere well to cardboard and can be very expensive compared to other packing tapes. You can use it for labeling boxes, but otherwise, look elsewhere for packing tape.
Gorilla Shipping Tape is thicker, tougher and wider! Keeping packages secure now takes JUST ONE STRIP! The smooth, quiet, ultra thick tape is easy to cut and apply, and holds for as long as needed.

Most often polypropylene tape is used for sealing cardboard boxes as well as PVC tape. Duct tape, on the other hand, is more suited to offering a temporary repair than keeping a box sealed. This type of tape tears very easily in comparison to its counterpart used in packaging.
When you use non-carton sealing tape to seal your packages, you risk having your boxes pop open or items falling out along the way. For example, masking tape is made of paper and is easy to tear, which makes it a poor choice for sealing boxes.
No. Duct tape doesn't work well on boxes because of the cardboard's porous surfaces. It also leaves a sticky residue when you unpack the boxes. You should always use packing tape, especially if you're sealing the bottom of boxes (use heavy-duty ones if you will be packing heavy items).
According to staples, the difference is: shipping tape doesn't have acrylic that packing tape does. They elude shipping tape is stronger, leaving me with the assumption that the addition of acrylic = less strong.
At the moment of application: The reaction that takes place as an adhesive sets is influenced by temperature; a higher temperature will speed up the reaction, which means that labels applied at higher temperatures will usually have better adhesion than those applied at lower temperatures.
Temperature can have a significant impact on tape performance. High temperatures can cause tapes to soften, melt, or lose their adhesion, while low temperatures can make tapes brittle and less effective.

You may need to wipe the plastic down with some rubbing alcohol to clean off the plasticizers so the tape can stick better.
There are several reasons why this could happen: Low surface energy: Polyethylene has a relatively low surface energy, which means that it can be difficult for adhesives to bond to it. This can make it challenging for some tapes to adhere to polyethylene surfaces.
