Thanks for your inquiry. I'll be happy to offer any assistance that I can.

The age of the label stock can certainly have an effect on the strength of the adhesion. If the labels have been sitting for years it's possible that the adhesive has hardened or weakened to some degree. Were the original labels purchased from us? If they were, and you still have the original packaging, I could check on the age of the labels using the lot number located on the product label.

We do offer label materials that have a more aggressive adhesive - some of our weatherproof options and our aggressive white matte feature adhesives that are a bit stronger that basic label adhesives. The standard materials and adhesives should work well on most glass surfaces though.

Please let me know if you'd like to receive samples of any of our materials. I'd be more than happy to have a few sample sheets sent out to you for testing.

Both of the lot numbers that you provided are over four years old, so the age of the product could definitely be contributing to the adhesive issues that you have experienced. I'm not surprised to hear that the label going on the metal lid is working properly - it's much easier to apply labels to a flat surface than a curved surface, even with weakened adhesive.

Based on the age of the product you are currently using, I have a feeling that the new products you ordered should work out much better. If you have any questions after receiving your order please just let us know.

Thank you for your business!

Our clear labels should stick well to a beer bottle. I recommend laser printing as opposed to inkjet printing since our clear inkjet labels are not intended to be waterproof. Also - If you are going to use a clear label on beer bottle, I recommend that you print darker colors since lighter colors may not be opaque enough to be readable against a darker bottle or a darker colored beer.

I highly recommend that you do some tests before making a purchase. We are happy to send you samples for testing if you would like to fill out our sample request form at the link below.

I was able to locate your account in our system and it looks like you're using the brown kraft label material. This is a pretty rigid paper-based material, so there can be challenges associated with adhesion on curved glass surfaces. There are a few steps you can take to ensure that the labels adhere as well as possible.

- You want to make sure you're labeling a clean surface. Any debris or residue will potentially cause issues, especially if you're labeling a curved container. Some customers choose to wipe down their application surfaces with rubbing alcohol to ensure that the surface is as clean as possible. This isn't always necessary, but can definitely help promote a stronger adhesive bond.

- If you're already working with a clean, dry surface the biggest factor relating to proper adhesion will likely be surface tension. Excess surface tension can cause a label to lift up at the edges. To reduce surface tension, you'll want to apply the center of the label first and then press outwards both ways to distribute pressure evenly/ This will ensure that the label is being applied with as little surface tension as possible and typically goes a long way toward reducing edge lift on labels that wrap around a curved surface.

- Label size can actually have an impact on the adhesive application strength as well. If your application surface allows for it, moving to a larger label size will increase the surface area of the adhesive and will typically result in better adhesion overall. If you're labeling a curved container you may want to consider a full wraparound label as well. Overlapping the edge of the label so that it wraps around and applies to itself can definitely improve the application strength. If you're going to overlap the edge of the labels, the key is to allow for enough length so that the overlap is at least a quarter of an inch. Anything shorter than that may result in some lifting, but if there's enough surface area on the overlap you should see excellent adhesion.

If you've tried all of the suggestions listed above but still need better adhesion you may want to consider one of our label materials with a stronger adhesive. Unfortunately, we don't currently offer a brown kraft option with a stronger adhesive, but our aggressive white matte and our selection of weatherproof materials feature adhesives that are typically stronger than a general purpose permanent adhesive.

I hope this helps. Please just let us know if you need any additional information.

I'm sorry to hear that you're having adhesive issues with the Weatherproof Polyester Laser (LP) material. This label stock typically has a strong, permanent adhesive that performs well on glass bottles. Below are our general recommendations to address common adhesive problems. Since you ordered a small batch, there may be an isolated issue with the sheets you received. If you’re unable to resolve the issue, please give us a call, and we can arrange for a replacement.

We recommend using Labels, Cardstock, or Transparencies as the paper-type settings for your printer when printing on film-based laser materials.

• Clean your hands and the application surface. Any debris, dust, moisture, or natural oils can interfere with the adhesive, weakening the bond.
  
• Apply the center of the label first and then work out toward the edges. This reduces some of the tension on the ends of the label which will help it stay down.
  
• Use pressure when sticking the labels to your surface. Our products are pressure-sensitive, so more pressure equates to a stronger adhesive bond.
  
• If the application includes an overlap with full coverage printing, make sure to leave the bottom side of the overlap unprinted. Ink and toner can make it difficult for the adhesive to fully bond.
