Are these labels perforated?

Yes, the RL2791XW is perforated between labels. You can view this and other details on the product page under Product Specifications.

Is this material like BOPP OIL/CHEMICAL RESISTANT

Our Weatherproof White Gloss (IW) material features a glossy white polyester film facestock that is designed for water resistance. We do offer our Weatherproof Vinyl (LV) material for certain sheet label configurations which is rated for resistance to chemicals if you would like to shop these for a better fit. https://www.onlinelabels.com/chemical-resistant-labels.htm If you'd like to try samples of either the IW roll labels, LV sheet labels or other materials, you're welcome to use our sample request form: https://www.onlinelabels.com/samples

Will these work with a Primera LX610? I assume they would, since you list the LX500 - just want to check before ordering.

The Primera LX610 requires rolls with a 3" core and 6" maximum outer diameter. Since the RL2791IW is a 2" core roll, it would not be recommended for your printer. We do, however, offer Primera compatible 3" core rolls which can be viewed at the link below: https://www.onlinelabels.com/materials/inkjet-roll-labels#g3CoreInkjetRollLabels

Hello, My Epson label printer will only take a 4" OD roll. Can this material be ordered in 4" OD sizes ? If not, what product does come in 4" OD sizes?

I apologize but for inkjet roll printers we do not offer any rolls that are smaller than the 5" outer diameter. If you need additional assistance, please reach out to Customer Support at 888-575-2235.

Are these labels removable without damage to cardboard box or carton surface?

The White Matte has a standard permanent adhesive so it may not remove easily from the surface once the adhesive has fully bonded. You are welcome to request samples if you would like to test this product before placing an order. I have included a direct link below to our sample request page. https://www.onlinelabels.com/samples

Do you sell CONTINUOUS 4" Roll Inkjet Labels - 2" Core / 5" Outer Diameter (not separate labels) that I can use on the Primera LX400/LX500/LX500C & cut to length myself? Matte or Gloss or maybe weather-proof???

We do not carry continuous rolls at this time. Below is a link to our available sizes for the Primera inkjet printers which are available in White Matte, White Gloss, Weatherproof White Gloss, and Weatherproof White Matte. https://www.onlinelabels.com/material_inkjet_roll_labels.htm
