I'm reaching out regarding custom burrito wraps. We need clarification on the type of material used. Are your wraps made of parchment paper or wax paper? Our preference leans toward parchment, as we intend to use them for pre-wrapped frozen burritos that will be heated in the oven. It's essential that the wraps can withstand high temperatures without compromising the quality of the burritos. We're looking for a product that ensures even heating and maintains the integrity of the food. Any additional details about the specifications, heating capabilities, and possible bulk order options would be greatly appreciated. Thank you!
