This involves gluing the pages of the book to a spine and then attaching a cover. It\u2019s called \u201cperfect\u201d because the pages and the cover are all cut to the exact same size, allowing them to line up perfectly during the binding process.<\/p>\n\n\n\n<p>Perfect\nbinding offers several advantages over hard-cover binding. These include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lighter<br>in weight<\/li>\n\n\n\n<li>Strong,<br>durable binding<\/li>\n\n\n\n<li>Lower<br>cost than hardback<\/li>\n<\/ul>\n\n\n\n<p>If you\u2019re wondering, \u201cwhat type of glue is used to bind paper?\u201d in <a href=\"https:\/\/www.printivity.com\/books\/perfect-bound-books\">pe<\/a><a href=\"https:\/\/www.printivity.com\/insights\/when-to-order-pur-perfect-bound-books\">rfect binding,<\/a> there are two basic methods to choose from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li> PUR (polyurethane reactive) binding <\/li>\n\n\n\n<li>EVA (ethylene-vinyl acetate) binding<\/li>\n<\/ul>\n\n\n\n<div class=\"wp-block-buttons is-horizontal is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-499968f5 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-background wp-element-button\" href=\"https:\/\/www.printivity.com\/books\" style=\"background-color:#ef4129\">Get Instant Quotes &#8211; Custom Book Printing<\/a><\/div>\n<\/div>\n\n\n\n<p>Both processes are used by print finishing companies. However, PUR book binding is rapidly overtaking EVA as the preferred method of perfect binding. If you have a print project that requires soft-cover binding, understanding the differences between the two methods can help you choose the correct binding technique for your needs.<\/p>\n\n\n\n<p>When <a href=\"https:\/\/www.printivity.com\/books\/pur-perfect-bound-books\">PUR binding<\/a> was first introduced, industry professionals debated over the merits of PUR vs. EVA glue. These days, PUR is generally recognized as the better binding process. However, there are times when EVA is a more appropriate choice. Both binding processes are very similar. In fact, the main difference between the two is the type of glue used to hold the book together (hence the PUR vs. EVA glue debate). However, there are other factors that come into play, including the thickness of the book, what the product will be used for, and the cost of the print finishing process.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.printivity.com\/landing\/insights\"><img data-recalc-dims=\"1\" height=\"256\" width=\"1024\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.printivity.com\/insights\/wp-content\/uploads\/2021\/07\/BannerBusinessCards-1024x256.png?resize=1024%2C256&#038;ssl=1\" alt=\"Get 20% off your first order at Printivity banner ad\" class=\"wp-image-2648\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>PUR vs. EVA glue<\/strong><\/h2>\n\n\n\n<p>An\nexamination of the perfect binding process starts with understanding the <a href=\"https:\/\/postpressmag.com\/articles\/2017\/perfect-binding-traditional-eva-vs-pur-adhesive\/\">differences between the two types of\nglue<\/a>.<\/p>\n\n\n\n<p>As\na polyurethane reactive material, PUR makes a highly effective adhesive because\nit can form strong bonds to many different materials. Its properties can be\ncontrolled, depending on the reactive components used. The bonds develop\nquickly and provide good initial bond strength.<\/p>\n\n\n\n<p>EVA is an ethylene vinyl acetate, or \u201chot melt,\u201d adhesive. It is polymer based and thermoplastic in nature, which keeps it solid at room temperatures. EVAs don&#8217;t require water or solvents to achieve their adhesive properties. This gives them a fast set time and a longer shelf life.<\/p>\n\n\n\n<p>Binding books with PUR adhesive is very similar to the traditional EVA glue perfect binding process. Different notching, roughing, and equalizing heads are used to create fiber. The adhesive then bonds with these fibers during the curing process. PUR properties draw moisture out of the air during the curing process, which creates a stronger bond than EVA. In fact, PUR bond strength can be as much as 50% greater than EVA once the adhesive application has fully set.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-horizontal is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-499968f5 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-background wp-element-button\" href=\"https:\/\/www.printivity.com\/books\" style=\"background-color:#ef4129\">Get Instant Quotes &#8211; Custom Book Printing<\/a><\/div>\n<\/div>\n\n\n\n<p><a href=\"https:\/\/duplointernational.wordpress.com\/tag\/pur-vs-eva\/\" class=\"broken_link\">PUR bonds<\/a> are also more durable, offering greater stability as the book ages. The binding is fully resistant to print ink oil migration and can bond to coated and uncoated stock. In addition, PUR doesn\u2019t experience the problems with extreme temperatures that can affect traditional EVA binding. Once cured, EVA adhesives can be reactivated with heat, causing them to melt. PUR creates a strong elastomeric film that isn\u2019t subject to reactivation. As a result, PUR won\u2019t re-melt under high heat. Conversely, EVA adhesives can become brittle and crack in extremely cold temperatures. PUR won\u2019t crack because it can\u2019t be reactivated. <\/p>\n\n\n\n<p>Not only is PUR binding stronger than EVA, but it is also more flexible. The inability to be reactivated after setting gives PUR its strength and durability. PUR binding applies a thinner coating of adhesive than EVA, which makes it more flexible. This superior flexibility enhances PUR\u2019s ability to lay the book flat without damage. Using less adhesive also creates less distortion of the spine and a cleaner appearance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why PUR beats EVA<\/strong><\/h2>\n\n\n\n<p>Both\nPUR and EVA offer good quality binding of soft cover printed materials.\nHowever, in terms of PUR vs. EVA glue, the advantages offered by PUR far\noutweigh those of EVA binding. <\/p>\n\n\n\n<p>PUR:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Requires less adhesive during the binding process<\/li>\n\n\n\n<li>Is more flexible than EVA and offers better lay-flat abilities<\/li>\n\n\n\n<li>Higher cold and heat resistance, allowing books to be stored and used in extreme temperatures<\/li>\n\n\n\n<li>Can bind a wide variety of paper stocks, including varnished, UV-coated, carton, recycled, and more<\/li>\n\n\n\n<li>Can\u2019t be damaged by oils used in the digital print process <\/li>\n\n\n\n<li>Doesn\u2019t allow ink migration into the spine<\/li>\n\n\n\n<li>Has better \u201cpage pull\u201d results compared to EVA<\/li>\n\n\n\n<li>Offers better handling of cross-grained stocks <\/li>\n\n\n\n<li>Provides a stronger bond, which is ideal for high <a href=\"https:\/\/www.printivity.com\/insights\/how-do-you-count-pages-in-a-booklet-for-printing\">page count<\/a> books<\/li>\n<\/ul>\n\n\n\n<p>EVA\noffers:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fast<br>curing of only a few seconds <\/li>\n\n\n\n<li>Lower<br>cost than PUR binding<\/li>\n\n\n\n<li>Ease<br>of operation<\/li>\n\n\n\n<li>Faster<br>cleaning of the binders<\/li>\n\n\n\n<li>More<br>cost-effective binding option<\/li>\n<\/ul>\n\n\n\n<p>EVA\nalso works better when binding thread-sewn books because the thicker glue does\na better job of penetrating into the spine area of the folded sections.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>PUR \u2013 The best in soft cover\nbinding<\/strong><\/h2>\n\n\n\n<p>At <a href=\"https:\/\/www.printivity.com\/\">Printivity<\/a>, we offer both glue options for our perfect bound books.
