The invention relates to a laminate comprising at least one layer a) comprising an oxygen barrier material, at least one layer b) adjacent to layer a), wherein layer b) comprises at least one ethylene-acrylate copolymer comprising recurring units derived from at least one acrylate comonomer represented by formula (I) or (II): CH2=CR1-COO(CH2)n-OH (I) CH2=CR1-COO(CH2)m-CHOHCH2OH (II) wherein R1 is H or C1-C5 linear or branched alkyl, n is an integer of 1-10 and m is an integer of 0-10.

RESEALABLE CONTAINER

A container including a tray and a lidding film is provided. The lidding film is removably coupled to the tray and includes a breakable layer, a lidding layer coupled to the breakable layer, and a PSA layer. A reseal portion of the breakable layer is sealed to a flange of the tray. The PSA layer is arranged between the lidding layer and the breakable layer. The PSA layer includes a reseal portion to adhere to the reseal portion of the breakable layer. The reseal portion of the breakable layer separates from an inner portion when the container is initially opened such that the reseal portion of the breakable layer remains sealed to the flange and the inner portion of the breakable layer remains coupled to the lidding layer. The container is resealed by adhering the reseal portion of the PSA layer to the reseal portion of the breakable layer.

BAG WITH HIGH WATER VAPOR PROTECTION
20250074659 · 2025-03-06 · ·

The present invention refers to a bag suitable for containing cement, or other similar material, made up of at least two paper sheets superimposed on each other, with a weight of 70-90 g/m.sup.2, of the semi-extensible type, i.e. with a tensile strength in the machine direction MD of 6.4-7.8 kN/m and a tensile strength in the transverse direction TD of 4.7-5.8 kN/m measured according to ISO 1924-3:2019

Each of said outer paper sheet and internal paper sheet is coated on one side with a water vapor barrier layer having a weight of 10-20 g/m.sup.2 measured according to the ISO 536:2019 standard,

The barrier layer comprises a styrene-based polymer dispersion and at least one pigment composed of clay and calcium carbonate.

The water vapor barrier layer is in turn coated with at least one hydrophobic paint layer of the water-based wax type, such as for example a polymeric wax, including at least one element of the isothiazol-3-one type, such as example 1,2-benzisothiazol-3 (2H)-one, 5-chloro-2-methyl-2H-isothiazol-3-one (CMIT) and/or 2-methyl-2H-isothiazol-3-one, and mixtures thereof.

In this way, both the transmission of humidity/water vapor (WVTR) and the absorption of water (COBB) are significantly reduced.

In fact, thanks to the water vapor barrier layer and the hydrophobic paint layer applied on it, the water is not retained by the paper, but slides away due to the high surface tension present on the treated paper.

The bag achieves these results despite having no intermediate plastic layers.
