Paper Mills
Packagers who have discovered the competitive advantage of value-added packaging frequently have Michelman coatings applied by their paper converter. Tier sheets, for example, are commonly coated at the converter.
Coatings that provide grease resistance, MVTR, water resistance and corrosion inhibition are applied to kraft paper by size presses. Fiber board mills apply coatings for water/abrasion-resistance and corrosion inhibition at the water box.
Properties That Affect Paper Mills
Catalyst P1: Catalyst P1 is one part of a two part silicone release coating. This coating system provides release for virgin-rubber, asphalt and gum based products from corrugated containers eliminating the need for costly plastic bags. This system is not gluable.
CleanGrip® 111: CleanGrip® 111 is an alumina based, nonskid coating designed to reduce the slipperiness of shipping containers by providing excellent slide angles. CleanGrip® 111 has a low pH that does not resolubilize ink and can prevent ink smearing. This product is gluable with both hot melt and cold set glues.
CleanGrip® 2100: CleanGrip® 2100 is a silica based, sprayable nonskid coating designed to reduce the slipperiness of shipping containers by providing excellent slide angles. Because CleanGrip® 2100 is easily cleanable, it takes the worry and mess out of running nonskids. This product is gluable using both hot melt and cold set adhesives.
Coating X300™ AF: Coating X300™AF provides high levels of water resistance and good moisture resistance for kraft paper. Coating X300™ AF protects food products from excessive moisture, freezer burn, and sticking. When diluted for mill application, it is an economical sizing agent. Gluability with hot melt adhesives is excellent, but cold set gluing is not recommended.
Coating X300™ Plus: Coating X300™ Plus provides high levels of water resistance and good moisture resistance for kraft paper with improved water resistance over Coating X300™. Coating X300™ Plus protects food products from excessive moisture, freezer burn, and sticking. Gluability with hot melt adhesives is excellent, but cold set gluing is not recommended.
HydraBan® 1000AF: HydraBan® 1000AF is an economical water based treatment for kraft paper. It imparts a high degree of water repellency, is printable and gluable.
HydraBan® 708: HydraBan® 708 is an economical, water based treatment for kraft paper. It imparts a high degree of water repellency, is printable and gluable. It can be applied at the wet end or dry end of the corrugator, or with an off-line treating operation.
Michem® Coat 40EAF: Michem® Coat 40EAF is a versatile water resistant coating which demonstrates some grease resistance as well. It is gluable with a wide range of water based and hot melt adhesives.
Michem® Coat 40Y: Michem® Coat 40Y is a versatile water resistant coating. It is gluable with a wide range of water based and hot melt adhesives.
VaporCoat® 2200R: VaporCoat® 2200R is a coating which provides water and grease resistance and excellent MVTR properties on kraft liner and other substrates. When properly applied over a base coat, this repulpable coating is recommended as a replacement for some curtain coating applications, poly-laminated board and plastic bags.
