Mylar: wavy covers issue 0

[elektrokuter]

Hi all, long time lurker first time poster.

I've finally taken the jump to bag and board a majority of my collection in Mylite 2's and Full Backs. 

I've started this process and noticed there are a good number of my books that have wavy covers on the top -or it seems there is too much air and the cover poofs in the middle of the book.

Basically not laying flat.

I am not sure what I am doing wrong so I'm wondering if you experts have any advice. I'll say this batch of fullbacks from Gerber has a lot of QC issues such as miscut/unven cut and/or too short boards and flaking but I dont think that's totally the issue. Below are some pics of random comics I was messing with. Thanks for any advice!

 

This one is just generally wavy

This comic kind of has the cover poof in the middle instead of lying flat

General wave and no part of this cover lays flat

Just another pic of the cover not being flat to the comic.

Sorry for the long-ish post.

Thanks again!

Welcome to the boards......  

Looks more like the comic rather than the board

I think looks fine err, normal

Looks to me like the bags are too tight 

I’m assuming the books lay flat when out of the mylites?

Or the bag and board are too loose, and that's why I thought it was just the comic. No modern comic lies so flat unless it's been pressed but just my opinion

If the comics are wavy outside of the bags....I’m confused as to what the OP is asking.

I'm sure he'll clarify but true, and I could be wrong

Could be static making the cover cling to the bag. That can result in waves.

sounds like he is saying that once he seals the mylar there is air inside, so a "poof and not too tight"

At the same time he's saying it "doesn't lie flat?" so maybe due to the poof? idk, the way he took pics I thought he meant the actual board, but @elektrokuter its going to rise in the middle due to the comic, not as flat as you might think.

If it poofs then there is room, and I think the comic looks normal. If too tight I think it would crimple the comic a lot more noticeable and in a more obvious and distinct way if too tight

Sorry for the late follow up, wasn't sure when the post would be approved so I got wrapped up in other stuff.

Thanks for the welcome!

To clarify: yes my books lay flat when they are out of the bag. I included some oddities in the pics tho just for larger sample size

Agents of Atlas is slightly wavy out of the bag, but even more pronounced when inside

Luna Snow has the very  slightest spine roll forming, but when in the mylar it has that weird wave pattern.

The Brightest Day and Marvel Boy are completely flat out of the bag as most of my comics are- but when inside they seem to get wavy or the middle of the comic seems to stick out (if you look at the middle of the Marvel Boy cover this is what I mean if it makes sense). But if the rise is what is supposed to happen then maybe I won't worry lol.

I thought it was static or something- I had one batch where the mylites were all oddly tight, but I've bagged more than that batch. I notice modern marvels with the crappy paper seems more susceptible to this than older comics with thicker cover stock.

Could this be from excess humidity in the house all though OP mentions they lay flat out of bag which is probably static or improper bag size.. but the one book that’s still wavy outside of the bags could that be a book exposed to too much humidity

That one book def had some damage. I guess I showed it more so to say the waves were even more pronounced when in the Mylar.

Is there any way to combat the static if that is the case? Or is it basically a non-issue.

To eliminate the air pockets I have found stacking the books seems to help a bit.

Usually the air is staticky from dry air so get a hydrometer and check the humidity level where ur storing the book storing comics you need to always be mindful of temp, humidity, light sources and storage material (acid free).

Ahhh got it. This makes total sense. I have an issue with foil trading cards warping due to the dry air. Unfortunately my place of dwelling is dry most of the year but can trap humidity in the summer if AC isn't on 24/7. I haven't been able to solve this.

you know at first I was like  over how it looked "that odd" for you to actually notice  

I guess I need to wake up and pay attention, I would have put it in the bag and board, eyed it, and never given it another thought

yours just didn't look that obvious

Haha- honestly I didnt notice at first either until I had to take them out again to re-arrange some boxes. I have a small amount of OCD and things like this drive me insane if I think something is wrong.

As long as you get some answers, it's at least food for thought

Yeah check humidity levels and if needed buy a humidifier and de humidifier and use either one to help maintain the humidity level.. if it gets humid in summer use a de humidifier to help you out with that but the hydrometer   Is a useful too they are like 20$ on Amazon too and will give u a idea of what to do etc

Hi, I'm pretty new to comics but have been using archival boards and 4mil beaded mylar bags from Bags Unlimited for my PC (I don't trade or sell).  I find my copper-age and moderns fit well using the same sizes.  Although they "fill with air" a little bit, they compress the book against the board really well.   "Wavy" books compress almost perfectly  flat.  One thing I noticed from your photos are that your bags and boards are quite a bit larger than the books themselves?  This may contribute to having more loose space in the bag allowing for wavy pages to remain thus?  These bags and boards I get are far from cheap but the protection is premium as far as I can tell.  

Oh, I should mention that these are made for storage and not for re&re'ing books.  It surely can be done but I don't bag them in 4mil until they're ready for their long sleep.  If you go for heavier mylar and tighter fitting boards, I suggest you practice inserting books with a couple of reader copies or something expendible if you're not accustomed to it.
