Polyethylene film lining. The film has antistatic properties and contains no additives such as Softeners or similar products that could react with the vinyl of the records. Lined sleeves are much smoother on the inside than unlined paper sleeves, a difference you are sure to notice immediately when removing and inserting your records.

“HDPE sleeves have major advantages over paper inners. Paper ones have one smooth side but one rough side, so that they can be printed on, and this means that they are more prone to marking the vinyl. Furthermore, a lot of collectors are unaware of the fact that a HDPE bag should have paper that looks old, not bright white. Pristine paper is more expensive and naturally yellower, ash-free and unrecycled, while bright white has optical enhancers, costs a third less, but is lower quality and, with continuous usage, will shed particles and leave paper dust on the vinyl.
 
As for the poly inner itself, you need to ensure that it’s not PVC – you can tell by its smell, which is produced by artificial softeners. Polyethylene  has no softeners, which can leach into paper or onto the vinyl, and though low-grade polyethylene can produce a white dust, HDPE sleeves will not,and they have the bonus of an anti-static additive that prevents vinyl from sticking to them. Static electricity attracts dust and you need to minimise its presence. Also, HDPE has a melting point of around 130C, so it’s stable in most heating conditions and it copes with humidity very well. 

RECORD CLEANING

EVERY RECORD IN YOUR COLLECTION SHOULD BE CLEANED BEFORE YOU PLAY IT AGAIN, AND EVERY RECORD ADDED TO YOUR COLLECTION SHOULD BE CLEANED BEFORE PLAYING.  

Every record, even if thought to be cleaned, is soiled with a wide range of dirts and contaminants, including mold and mildew. Vinyl discs are also coated with sticky  compounds.removing pressing debris and 'mold release compound' from sealed LP Contaminants between the groove and diamond styluse cause mistracking and are abrasive resulting in unnecessary, excessive wearing of both record and stylus. By interfering with proper groove tracing, dirty records produce inaccurate, noisy sound.

Resulting in reduced sound quality

Reduction in Stylus Life span

Increaesd  Record wear

Increasing  Static , pops & Clicks

Clean all your records

1/ Manually with a commercial record cleaning fluid & Wet Record Brush
