Improving recycling of polyethylene-coated paperboard with a nanofibrillated cellulose layer

, 2021
To improve the ability to recycle polyethylene (PE)-coated paperboard, one solution may be to use nanofibrillated cellulose (NFC) to generate a layer that should weaken when wet that leads to a clean separation between the polymer film and the pulp ...

Humidity effect in heating and cooling of press‐formed paperboard food packages: Comparison of storing and heating conditions

Packaging technology & science, 2021
Press‐formed paperboard food packages were heated and cooled to study the humidity effect on the packages with a series of dimension measurements. The empty packages in the form of trays were pre‐dried or preconditioned before their packing with oatmeal,

Nanocellulose addition to recycled pulps in two scenarios emulating industrial processes for the production of paperboard

Maderas: Ciencia y Tecnología, 2023
This study assesses the incorporation of nanocellulose in a paperboard feedstock emulating two scenarios of industrial processes. It included the production of 170 g/m2 paperboard, using mixtures of short-fiber and long-fiber fractions from recycled ...

Investigating the Performance of Polytetrafluoroethylene and Polyoxymethylene Creasing Rules in the Package Conversion of Coated Paperboard

Packaging Technology and Science, EarlyView.
Two sets of creasing tools were designed and machined from polytetrafluoroethylene (PTFE) and polyoxymethylene (POM) in this study to improve the creasability of commercial dispersion‐coated paperboard. Their performance was evaluated by measuring the oil and grease resistance of the samples before and after creasing/folding and comparing the results ...

Activating Paper Applying Gelatin, Starch and Chitosan Coatings Loaded With O/W Emulsions Encapsulating Rutin, Carvacrol and α‐Tocopherol

Packaging Technology and Science, EarlyView.
Emulsion type governed the microstructure and functionality of papers coated with biopolymers matrix loaded with hydrophobic bioactives encapsulated into O/W emulsions. Emulsified systems improved UV–Vis barrier and antioxidant activity, whereas gelatin coatings with conventional or Pickering emulsions provided the greatest mechanical reinforcement ...

Anisotropy in Dry‐Type Valve‐Side Bushings of Converter Transformer: Phenomena and Effects

High Voltage, EarlyView.
ABSTRACT The safe and stable working of dry‐type valve‐side bushings, important components of converter transformers, is essential. In recent years, poor design has led to several core breakdown, flashover and cracking failures. The bushing cores, composed of crepe paper and aluminium foil, exhibit significant anisotropic physical properties due to its

Residual Life Assessment of Oil‐Immersed Insulating Paper by FTIR Feature Interpretability Evolution

High Voltage, EarlyView.
ABSTRACT The ageing of insulating paper escalates the peril of insulation failure in oil‐impregnated‐paper power equipment. Consequently, the real‐time monitoring and non‐destructive assessment of insulating paper condition assume paramount significance.

Flexo‐printable glucomannan‐based biofilm

Coloration Technology, EarlyView.
Abstract Biofilms were synthesised from glucomannan and xylan. The ratio of glucomannan: xylan varied from 90:10 (g/g) to 70:30 (g/g). Nanofibrillated cellulose was added to enhance the mechanical properties of the biofilms. In another approach, glucomannan/xylan suspensions were crosslinked with tartaric acid (TA) or citric acid (CA).

Effects of folding numbers, scoring depth and bending velocity on bending-moment relaxation of creased paperboard

Mechanical Engineering Journal, 2014
This work deals with the time-dependent creasing characteristics of coated paperboard. The correlation between the bending strength (resistance) and time-dependent problems on the actual processing phenomenon has not been sufficiently discussed in the ...
