I haven't looked at any pictures of your press, but an alternative to 
bags might be to what we use for grapes.  

We have a hydraulic basket press and to help elimnate "blowouts" we 
wrap hardware cloth (i.e. nylon window screening) around the the 
inside of the basket extending to the base of the press.  In our case 
the crushed/stemmed grapes are usually pumped directly into the 
press, but we have used an old stock pot to "ladle" the juice into 
the press.  Sometimes some pomice escapes from the bottom or the 
inevitable rips in the screening, but we keep a seive between  the 
press and the tub that catches the juice.  We then settle the juice 
overnight and ferment the cleared juice.  The screening usually lasts 
about 2-3 years.
