CASE Envy? Sheet Protectors

Available in either polyester or polypropylene, these plastic sleeves will hold and protect your print. Sheet protectors can be cleaned with isopropyl alcohol (rubbing alcohol) and a soft cloth. Rotating sheet protectors within your book will help to avoid concentrated wear. Sheet protectors are subject to "wear and tear" and should be replaced regularly to maintain the maximum level of presentability. The maximum recommended number of prints displayed per side is one.

POLYESTER SHEET PROTECTORS
These super-clear thin polyester sheets open on the top and the bottom. Non-yellowing at ambient temperatures and chemically stable, Case Envy™ Polyester Sheet Protectors are glossy, with high-tensile strength. A single package includes 10 sheet protectors with 10 pt. black acid and lignin-free paper inserts.

POLYPROPYLENE SHEET PROTECTORS
Soft and flexible, Case Envy™ Polypropylene Sheet Protectors have a slightly frosted, matte appearance to diffuse reflections. Each sheet opens only on the top and includes a 10 pt. black acid and lignin-free paper insert. A single package includes 10 sheet protectors.

DETERMINING THE PROPER GUTER WIDTH
Creating a gutter (the space between the printed area and binding) is the best means for achieving a portfolio with pages that lie flat. Consider the relationship between the gutter and the number of pages: if you add more pages, you will need a wider gutter, which will result in trimming your pages. Refer to the chart below as a guideline for your measurements when trimming your pages. Exact specifications may vary depending on your paper weight. It is recommended that you pretest to determine the dimensions most suitable for your portfolio.

SUGGESTED GUTTER WIDTH SPECIFICATIONS
WHEN USING 10 - 20 PRINTS MORE THAN 20 PRINTS
Polypropylene 1/4" 1/4" - 1/2"
Polyester 1/4" - 1/2" 1/2" - 3/4"
