Perfect 45 inner sleeves!

Perfect 45 inner sleeves!

A quarter of a century ago – or even more now- I ordered my first big lot of 45 inner sleeves from a small ad in Goldmine magazine (one of the very few sources to find stuff like that back then before the internet days). I soon forgot where i bought that sleeves from and with every new order of other polylined 45 sleeves from different providers in Germany, UK and USA I found out how perfect those sleeves actually are.

pure paper sleeves do mechannically harm the records (paper scuffs !!!) and while slowly decaying, sever wood fibre dust is piling up in the recordgrooves.

Paper scuffs & woodfibre dust. Typical for paper record sleeves

“Rice paper” or “Nagaoka style*” sleeves are High-density polyethylene (HDPE) without additional paper …and they are are too flimsy! They are antistatic, free of softeners (and other vinyl destroyers) and produce no dust, but they do wrinkle if you put the record back into the outer sleeve. Plus: due to their much thinner material too delicate to handle in time while dj’ing.

*The term “rice paper” is confusing since it’s material is not paper but plastic. I never spotted a recordsleeve made out of actual rice paper. Nagaoka is a well known producer of this kind of LP sleeves, but since they don’t do 45 ones, some sellers  call’ their 45 versions “Nagaoka style”

polylined paper sleves: Most of them are just too thin, often not antistatic wich causes audible crackles and pops while listening and keeps the record magnetic to the slipmat and every single dust particle around. The label might be hardly visibe due to the often corruated and milky plastic, typically the size is not precise and often too large to fit into standard cardboard outer sleeves, and -most important-  the polylining and the glue can destroy your records! Some of them do really chemically react with the vinyl if you wait long enough. I always thought they wouldn’t use that kind of acidic material anymore since they found out about that issue . Unfortuately some budget producers still do.

Most poly-lined inner sleeves are not suitable for professional use! If you don’t have all the time in the world but rather try to put on another tune every two or three minutes, all regular sleeves i ever experienced hardly slip back into the cover without getting stuck, warping and wrinkeling the paper thei’re made off (causing clumpy paper/plastic areas wich do press into the vinyl), ripping the paper off the plastic or just fall apart soon after you bought them.

The Sleeve City heavy duty sleeves are still fully intact. I don’t remember exactly if i bought 500 or more. About 10 sleeves all together broke by split seams, one got spilled with booze: it didn’t survive but the record perfecty did … wich is the innitial reason to have such things! and all the rest of the sleeves still perfectly do their job!

The inner lining of the discussed sleeve is thick and sturdy, made of hi-density polyethylene (HDPE). It’s feel is like cellophane as from japanese gift wrappingfoil. The paper is quite thick and dense. Neither the inner lining itself as well as the glue didn’t react in any noteabe way after all those years. Only some yellowing of the paper and that’s it. They do fit perfectly  inside the UK cardboard outers. Some records I played frequently over the yeas must have slipped in and out of the sleeves many dozends of times and there’s no evident sign of wear such as paper scuffs. Try this with a paper-ony-sleeve.

I finally found them super sleeves again at Sleeve City who made them back in the days – and they still do in the same top quality!

They are costy (roughly $0.25 a piece plus shipping etc) but i promise it is a much better investment than cheap ones that bother by short life span, laborious handling and ruin your records in the end.
