Where to Buy Quality Comic Sleeves
Some collectors opt to keep their comics as pure collectible items and won’t grade or slab them.
Bags provide your books with protection from dust intrusion, casual moisture build-u, and UV ray damage (depending on which type of bag you select, while also being obvious. Check out https://www.busteperfumetti.it/ to know more.
Boards provide stiffness and help prevent bending or curling during storage. Unfortunately, however, they’re not as protective as bags or slabs.
Polypropylene
Polypropylene plastic is one of the most versatile forms of plastics, used in an assortment of applications across industries and consumer applications such as flexible and rigid packaging materials, consumer goods like colanders and cutting boards, outdoor rugs as well as bumpers/instrument panels in automotive applications and disposable syringes/diagnostic devices in medical fields.
Polypropylene plastic stands out among other plastics by being colorfast ch, chemical-resistant, and easy to maintain; its inactive dye sites prevent dirt absorption or staining. Furthermore, polypropylene recycling rates are high,h and its low threshold for flammability makes it suitable for low-temperature environments; however, it has a lower melting point than PET or HDPE, which limits its application in high-temperature situations.
Polypropylene plastic is made by using monomer propylene extracted from hydrocarbon fuels such as petroleum oil. Once removed, this monomer undergoes chain-growth polymerization, which creates polypropylene. Giulio Natta of Italy first discovered syndiotactic polypropylene production catalysts similar to those Karl Ziegler of Germany did when synthesizing polyethylene. He began commercial production of his product in 1957, and it continues today.
Comic sleeves made of polypropylene are the most widely available on the market, but they can often lead to sticking and rippling over time and fail to diffuse natural gas emitted by paper over time. Both factors can contribute to the degradation of a comic over time, so mylar funny sleeves provide optimal conditions for the storage of comics by protecting them from external pollutants like UV light and moisture and resisting internal gas diffusion.
Mylar
As a collector, your comics must remain free from damage caused by handling and environmental factors. A simple solution for protecting them from this damage is placing them into comic book sleeves, which offer both handling and environmental protection. Polypropylene and Mylar are among many different varieties available that all provide adequate protection.
Polypropylene comic sleeves are an economical and long-term choice, yet they don’t offer sufficient UV protection against sun fading or the natural gases emitted by paper, which degrade comic books over time. Therefore, it would be prudent to replace polypropylene sleeves every three to eight years to protect their contents adequately.
The polyester film provides slightly more excellent resistance to sunlight damage. Mylar, which stands for biaxially oriented polyethylene terephthalate (BoPET), is one of the most renowned polyester films used for food packaging and archive storage applications.
Mylar is considered the gold standard when it comes to storing paper collectibles and is even used by the Library of Congress. Although more expensive than poly bags, Mylar provides maximum protection for comic books.
Mylar sleeves can be found at stores such as BCW Supplies and Bags Unlimited, some even containing acid-free board inserts – perfect for adding acidity-free boards into any comic bagged and boarded comic collection! Additionally, desiccant packs that indicate when they need to be recharged will change color to indicate this need.
The BCW Thick Comic Sleeve features a 1.5-inch resealable flap, made of thicker plastic than regular BCW resealable comic bags and ideal for older comics that surpass 22 to 32 pages in page count. Plus, its reduced chance of creasing or tearing makes it perfect for long box storage!
Boards
No matter whether you collect comics for entertainment or investment, they should always be adequately protected against environmental damage. That’s why sleeves were created: thin polypropylene or mylar films that watch comic books against dust, moisture, and UV rays. There are three varieties of sleeves depending on your need: polypropylene, polyethylene, and Mylar sleeves, which are typically available. Polypropylene is the least costly but lacks airtight properties to prevent moisture seepage over time.
Polyethylene is an economical and sturdier alternative to polypropylene, boasting lower costs while providing more protection than its cheaper counterpart. Mylar stands out as an archival material of choice with thicker walls that don’t attract dust as easily and an antistatic charge that discourages dust or hair collecting – so much so that even the Library of Congress uses Mylar to save its documents!
For long-term storage of comics, they should be bagged and boarded. Bags will help minimize handling defects caused by holding comics over time; boards keep them stiff to prevent them from bending over time. To ensure optimal results, choose acid-free boards coated in calcium carbonate, which absorb and neutralize any acids paper decay produces. These boards can be purchased from companies like E. Gerber Products and BCW Collector Supplies; many comic shops also provide acid-free boards explicitly cut to your needs. You may also wish to invest in some funny book extender sheets; these ultrathin sheets absorb and neutralize odors, acids, pollutants, and harmful contaminants inside the front and back covers of valuable comics before bagging and boarding them.
Soft Slabs
While slamming comics is the ideal solution to protecting them, it may not always be practical or affordable. Slabbing costs money and is not airtight – intentional as this allows natural degradation processes to continue rather than accelerate.
Not everyone likes the look or is comfortable trusting freight carriers with their valuable collection, such as modern-era comics that do not hold much monetary value. Slabbed books may also cause discomfort.
Soft slabs offer an alternative way to have your comics slabbed. Similar to bagged and boarded comics, you have more flexibility with regard to storage options. Thanks to being able to open them yourself, soft slabs can be found at most major retailers and online.
If you have ever had your comic graded and slabbed by Comics Guaranty, LLC (CGC), you may have seen that they come enclosed in plastic “slabs.” While this provides superior protection from environmental damage, its downside is not being able to access and scan your collection.
If you don’t have the budget or prefer being able to access your comics easily, an alternative would be buying soft slabs and adding desiccant sheets from BCW Supplies to them. These sheets help prevent the yellowing of paper and ink by retarding aging; costing around 10 cents each, they should only need two per comic book.
Top Loaders
Some collectors choose top loaders – heavy plastic sleeves designed to protect comics from further bending or other forms of damage – when purchasing their comics bagged and boarded in plastic sleeves for additional protection from bends. Each top flap contains a sticky strip to secure it tight against its contents – this cheaper alternative to slabs offers reliable protection at an economical cost.
Consider how seriously and long you plan on treating your comics before selecting either slabs or top loaders as the appropriate option for storing and protecting them. A slab is recommended if you care deeply for them and wish for them to look their best when displayed or read since its protective layer prevents internal gas diffusion, which could otherwise cause degeneration to the paper over time while keeping light off it and helping prevent discoloration or fading of comics over time.
Polyethylene mylar sleeves may also be helpful, being more expensive but providing optimal protection from sunlight and environmental factors that degrade paper collectibles. Library of Congress documents are stored using this kind of material, and their low static charge makes inserting and extracting comics easy without damaging their covers.
When selecting your brand of comic bag storage solution, ensure it is acid-free and does not contain PVC. Some companies like Ultra Pro and BCW produce acid-free bags; cheaper brands may tempt you, but over time, these could degrade paper within your comics and cause wear-and-tear damage to them. To protect them even further, opt for one with acid-free tape attached directly to the inside of the bag; while it might cost slightly more, it is worth every penny of investment!
