Collecting vinyl is a hobby that can lead you to the craziest of places. Antique stores, book shops, and yard sales are all places to find some of the best music out there. The downfall of finding hidden vinyl gems is often times the record sleeves. Scratchy paper, wrinkly plastic, or having no sleeve at all can be detrimental to the record, so having some nice inner sleeves on hand is always a good idea.
There's no question that the Mobile Fidelity Original Master inner sleeves are the best on the market. They're safe, and protect the integrity of the vinyl more than any other sleeve out there. Highly recommended.
Rice Paper Record Sleeves
In response to rapid advancements in both recording formats and audio delivery systems over the past several years, Mobile Fidelity has maintained its ongoing commitment to improving industry standards. This has resulted in the introduction of numerous innovations in the audiophile arena: half-speed mastered Original Master Recording™ LPs, Ultra High Quality Records™ (UHQRs), high fidelity cassettes, consumer alignment devices for phono cartridges and audio cassette decks, Original Master Recording™ compact discs, the 24-karat gold plated Ultradisc™ CD and the Ultradisc™ Ultra High Resolution™ (UHR). To this day the independently owned firm continues its commitment to exceeding industry
A natural need for Mobile Fidelity is non-abrasive, non-paper inner sleeves for its LPs. Pressing plants can supply them, but MoFi didn't go this route in the past, instead doing its own thing to protect its records: a rice-paper sleeve covered by a folded light-cardboard protector that conveniently announced upcoming titles. The Mobile Fidelity-branded sleeves you can buy today package of 50 are identical to those used for the records -- and identical to others that replicate the long-discontinued three-ply Discwasher VRP sleeve. However, when faced with the choice of MoFi sleeves or no-name equivalents, I admit to buying the MoFi, even at slightly higher cost. There's just something reassuring about sliding a record into a sleeve with the Mobile Fidelity name on it. Besides, the printing quickly lets you know which side is which and where the opening is. - Audiobeat

Polyethylene , Polypropylene , PVC & Mylar . To facilitate your choice, we created this page to explain the characteristics of these Four materials:

Polypropylene (PP) Anti-Static & are ideal to highlight your records, thanks to their very high transparency and Glass like brilliance. The polypropylene Outer is very smooth and soft but also not as soft as the poly Outers This is because polypropylene is a harder material than polyethylene. Polylypropylene Provides cost-effective Long-Term Archival safe protection for all of you records - Acid Free , Crystal Clear Glass Like Material & 100% Transparent .

It is a sturdy film that will give extra support to fragile documents.. Polyester is used worldwide in museums, libraries and archives. Polyester material is approved by the Library of Congress for archival storage. This material has passed the Photo Activity Test. PAT

It is nevertheless a safe bet that 99%+ % of Audiophiles & Record Collectors would agree that LPs shouldn't be stored in plain paper sleeves. Cheap, non-acid-free paper sleeves degrade with time. Paper is derived from the cell wall of plants; lignin, one of the chemicals contained in the cell walls, is unstable and light sensitive and decomposes into acidic products. While bleaching removes the lignin, the paper making process produces other detrimental byproducts such as hydrochloric acid or sulfuric acid.
Producing true, acid-free paper (pH >6) requires buffering with neutralizing chemicals. Paper sleeves are also hygroscopic (water absorbing) and as a consequence facilitate the growth of mold or fungus on the LP. The rationale for storing and preserving vinyl records in high quality, chemically inert, inner sleeves includes:Neutralizing the record's static charge and preventing static buildup when pulling the LP out of the record sleeve Preventing the record jacket or dirt from scratching the record
Long-Term Archival safe protection for all of you records - Acid Free , Lined , Anti-Static Inner Sleeves
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.
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
