Last year, Sappi invested over €60 million in the modernisation of paper machine 2 (PM2) at its Alfeld plant. This investment enables the company to achieve long-term, sustainable expansion of its range of speciality papers. The recently introduced Algro Vitess is a new paper for flexible packaging applications – Sappi Alfeld’s response to growing market demand for a very brilliant paper that can meet the most stringent printing requirements.
Algro Vitess is designed for both flexographic and gravure printing. The development of this paper leveraged Sappi’s expertise in optimum pulp composition and coating applications, as well as experience gained with its already- established Algro Finess®.

Thanks to the newly installed head box on Alfeld Mill’s PM2, Algro Vitess offers excellent forming of the paper fibres, resulting in minimal blushing. The paper also offers exceptionally high web stability and very low shrinkage. These properties make further processing by converters, including printing, lamination and extrusion, highly productive. They also contribute to an optimised packaging process for branded goods manufacturers. Its highly stable running characteristics allow faster processing speeds and higher quality results to be achieved throughout the packaging supply chain.

Exceptional Print Quality for Multiple Packaging Applications
The extremely homogeneous surface of Algro Vitess ensures exceptional print quality. This, combined with its extreme brightness, delivers outstanding on-shelf presentation for branded packaging. The reverse side of Algro® Vitess is designed to offer very good anchoring properties for both adhesive and extrusion laminations.

Algro® Vitess is coated on one side and is available in various weights, ranging from 50 g/m² to 120 g/m². It is suitable for a wide variety of packaging applications, including dry food products, confectionery, tea, coffee and pharmaceutical products. Initial results from pilot projects confirm the excellent properties of Algro® Vitess and praised its high brightness and excellent print results.

Food migration issues have arisen as a result of packaging materials containing recycled fibres for which one of the primary raw materials is newspapers. Newspaper printing inks contain mineral oil as solvents, as do many commercial printing inks. During the recycling process only 90% of the printing ink components can be removed.  If these substrates are used for food packaging applications, the mineral oil compounds can migrate from the cardboard into the foodstuffs, even when an inner bag is used. Especially dry and greasy foods such as rice, pasta, cereal and chocolate products are affected.

Developed in partnership with BASF and Eurofins, the innovative flexpack substrate received very positive market feedback following its introduction at Fachpack 2013. Brand owners are now able to use their current recycled fibre based folding boxes, shelf ready packs and transport boxes.  The food inside will be protected by inner bags, pouches and sachets made from Sappi mineral oil barrier papers such as:

• Leine Guard M for inner bags combines Machine Glazed Bleached Kraft (MGBK) paper with the mineral oil barrier on the reverse side. It is available in 80 g/m²  to 120 g/m².
• Algro Guard M has been designed for gravure printed primary packaging such as pouches, sachets, bags and wrappers, and is available in 90 g/m² to 140 g/m². This grade incorporates a blade coating on the top side for gravure printability with the mineral oil barrier on the reverse side.

AlgroGuard M and Leine Guard M protect packaged food from mineral oil compounds that are a complex mixture of saturated hydrocarbons (MOSH) and unsaturated hydrocarbons (MOAH). This new mineral oil barrier functionality protect food for minimum 15 months; and as there is no use of PET or aluminium, it is a sustainable, environmentally friendly and cost effective material.

Efficient and sustainable substrate

“The integrated solution of mineral oil barrier functionality combined with excellent heat sealing properties minimise converting process steps and considerably reduce costs in the supply chain.” comments René Köhler, Product Group Manager Flexpack Sappi Fine Paper Europe.  In addition the integrated and recyclable paper grade solution is providing superior converting properties. Test have shown that the grades offering also a barrier against aroma and grease. As a result, Algro Guard M and Leine Guard M are highly efficient and sustainable mineral oil barrier packaging solutions for the food industry. Sappi Algro^® Guard M and Leine^® Guard M, will become commercially available beginning of June of 2014.

Sappi Fine Paper Europe is targeting new markets with an expanded weight range in its Algro Sol portfolio of release liners following the successful €60m transformation of Alfeld Mill’s PM2. The development of the effective lightweight efficiency liners has been made possible by the new 135-ton, 6.4 meters in diameter MG cylinder recently installed on PM2 in the Sappi Alfeld mill. It produces excellent high dimensional stability and surface properties of Algro Sol papers that favour converting.

In addition to the well established Algro Sol DN weights of 120g/m²  and 135g/m²  Sappi is launching new weights of 70, 80, 85, 90 and 98g /m². All are offering a significant price performance ratio and are mostly suited for office use, tape and industrial applications. All grades are available in different shades.

Performance reliability a key feature

One of the main benefits of the dimensional stability is performance reliability, which goes excellent with lay flat properties. With some substrates, paper dimension in cross direction can expand by 2% or 3% as a result of temperature changes. With these grades the value is only 0.4% – this ensures consistency and runability.

“The rebuilt machine was designed to enable highly flexible production of a wider range of grades,” comments Gunnar Sieber Sappi’s Product Group Manager Release Liner. “The expanded range of lower Algro Sol DN weight papers offers a greater array of options and applications. We are excited to be presenting these to more target markets such as pressure sensitive adhesives and prepreg applications.  Along with how the grade can support a broader variety of end uses, we are looking forward to approaching new sectors we have not targeted with these grades before. We will also be looking at our global positioning.”

PM2’s flexible production capability will enable Sappi to develop grades to address opportunities as they arise. It is with this in mind that Algro Sol’s expansion is not stopping there.  Algro Sol CN will be the newest family addition comprising of lighter weight grades from 50 g/m² to 60 g/m². These papers are suitable for pressure sensitive adhesive office material applications.

As a competence centre, Sappi Alfeld Mill enables customers to further discover how the wide range of grade options can help them support their customer’s needs. They can also call on technical advice if required.

“PM2’s successful rebuild will enable us to better address customer requirements for higher quality grades while the additional production capacity will aid on time delivery and substrate flexibility,” concludes Mr Sieber.  “We will carefully explore all the opportunities this presents  and see how new variations of release liners can help us effectively embrace emerging opportunities.”
