Paper labels

In addition, dimer-type black developing fluoran compounds such as 2,2-bis(4-[6 -(/V-cyclohexyl-/V-methylamino)-3 -methylfluoran-2 -yl-amino]phenyl propane (59)60 are also proposed. Fluoran 59 has much lower solubility in organic solvents to improve image stability to plasticizer for use in thermosensitive recording label paper. 

Experimental larvae were allowed to feed on sample trees until pupation All larvae pupated within about three weeks after placement on the trees Near mid-July, bags were cut from the trees and transported to the laboratory. Pupae were removed from the bags, placed in labeled paper cups, and sealed with... 

Most label papers are chemical pulp, with additives, only. Most box boards are layers of mechanical or semi-chemical pulps with chemical pulps on the face and sometimes the back facings. Corrugated will probably, today, be nearly all recycled material, whereas unbleached semi-chem would have been used in the past for the corrugated medium. Any Kraft facing paper will probably still be 80-90% virgin Kraft pulp in make-up. 

Best paper for the purpose, i.e. white, tinted, coloured, coated, substance (most label papers between 60 and 110 g/m2), etc. 

They consist of a suitable label paper coated on the reverse side with a permanently tacky adhesive which is in contact with a backing paper that protects it prior to use. The backing paper is coated with a special release coating which permits the label to be removed easily. Labels may be provided in reel or sheet form both can have the label laid on , i.e. the non-printed area has been cut and removed. Sheet label forms also exist as split top type—both printed and non-printed area is present but printed area is split away so that it can be removed. Split back type has the backing paper split or cut so that it can be removed. (Applies to larger sizes.)... 

Grain direction. The grain of paper has been mentioned several times already, but with lightweight papers it becomes once again a critical feature, as the papers are both thinner and weaker than label paper or board. 

Polyvinyl acetate polymer is generally a soft, flexible and low melting polymer. Copolymers with vinyl chloride combine the properties of the softness of PVA with the hardness of the former. PVA and copolymers find use as an adhesive (labelling paper to metal or plastic), and a heat sensitive base. 

Chem. Descrip. Butyl acrylate/styrene aq. copolymer dispersion Uses Binder for label paper coatings and as clear coats on paper where abrasion resist, is required Features Exc. alkali, abrasion, and water resist.

It is important that the grain of the label paper is correct and that the appropriate adhesive is applied. The label has to adhere readily and effectively, remain in place during its journey to the customer and in dry or wet storage. Finally the label must detach easily in the bottle washer. Adhesives include (/) dextrins, ( ) jelly gums and iii) casein which will retain the label even if the bottle is immersed in ice-cold water. 

The label is an important part of the pharmaceutical product. The most common label used within the European pharmacy is the self-adhesive label. This consists of a laminate of two special types of paper the carrier material and the label paper. The carrier material consists of paper on which a silicon layer is fixed. The label paper can be printed on the printing side and on the carrier side it has an adhesive layer. The adhesive is usually of the permanent type, rendering the label non-removable once applied [25]. Label adhesives on plastic containers such as infusion bags require additional attention, see Sect. 24.4.13. 

Chemical History of the Resin Formulations. The most straightforward solution to track the chemical history during split-and-pool synthesis is labeling paper disks," T-bags, wafers, or capsules with an alphanumeric code... 

This is a specialty and particularly effective filler. It is appHed in specialty papers, often at low basis weights, with particularly high demand in dry and wet opacity and sheet brightness. Ti02 can be found in thin print paper, i.e. bible paper, high opaque grades, label paper and decoration paper. 

Silicone base papers are used as carrier papers for the later application of a onesided or two-sided layer of silicone, onto which, in the following operations, further layers, e.g. adhesive in combination with label paper, are applied. Silicone base papers presuppose special quality features. These include, above all, high compaction, uniform caliper and moisture, high transparency, strength, good flatness and a low surface roughness which ensures that the later application rates of the cost-intensive silicone are minimized. The basis weight of the silicone base paper is between 60 and 160 g m . As in the past, these papers are calendered offline on special supercalenders with at least 15 rolls. The resilient rolls consist of a...
