What size mailer do you need for an LP? You can stack LPs perfectly in a mailer that is 33.5 inches wide, 33.5 inches tall, and 35 inches long. The length of the mailer determines how many LPs can safely fit. What is the best way to package LPs for shipping? LPs are vulnerable to both heat and impact. The best way to avoid heat is with an insulated mailer. The best way to protect against shock and impact is with packaging foam rolls. Foam rolls also offer insulation that mitigates heat damage during shipping. How hot is too hot for LPs? Heat can melt LPs at high enough temperatures, usually above 200. The greater risk for LPs is warping, which begins at a mear 140. During hot weather, the cargo area in a shipping truck can easily exceed 140, so you need something that keeps the LPs cool if you use standard shipping. Conversely, you can look into climate-controlled shipping. Such trucks use insulation and cooling to ensure that the cargo area never reaches dangerous temp
