Film faced plywood, Length : 6ft, 7ft, 8ft

hello dear Sir
we have best quality Russian plywood all types -film face , Plywood Grades A & B
The highest quality - and most expensive - types of softwood plywood are the A & B grades and Plywood Grades C & D
The more economical types of plywood are the C & D grades. MDF (Medium Density Fiber Core) Medium Density Fiber Core Hardwood Plywood (MDF)
MDF is made from fine wood dust mixed with a binder and heat-pressed into panels. The sheets can be sold as-is, or a veneer skin, like oak or maple, can be laid up on the sheet. (The veneered sheet is the most common form, but blank MDF sheets are available as Paint-Grade)
This material is extremely stable to work with, and is typically very consistent from batch to batch. A 34" thick sheet purchased over a year ago is exactly the same thickness as a new sheet purchased today. The surface below the veneer is typically free of voids and blisters, resulting in a better veneer consistency and bond. With this better bonding of the wood veneer, there is less chipping during a crosscut operation. I have also observed that this material is easy to machine either by saw or router, and the cut edges are excellent for glue adhesion. (I have heard it mentioned that MDF is hard on cutters, but personally, I disagree with this statement. I feel that MDF is rather easy on the cutters.)
The primary drawback to this product is weight. A 34" x 4' x 8' sheet can weigh as much as 70 to 90 pounds per sheet. The density of the core is expressed as the weight of a one cubic foot (1'x1'x1') block of the material. Therefore, an MDF sheet using a 48# (pound) core, will weigh 96 pounds. (48"x96"x34"= 2 cubic feet)
Medium- and High-Density Overlay Plywood (MDO and HDO)
MDO and HDO consist of a core material, like laminated fir veneer, overlaid with a pressed fiber material. In short, this is a typical veneer core plywood (common plywood) with an MDF surface. This gives the best of both worlds;
