Recyclable films having at least a first layer containing a high-density polyethylene and a nucleating agent, a second layer containing a high-density polyethylene and a third layer containing a high-density polyethylene and a nucleating agent may be used for thermoforming packaging components. The film structure is advantageous as it can be more easily thermoformed that traditional high-density polyethylene films and can maintain the shape taken during thermoforming, exhibiting minimal warping or shrinking.

Recyclable film for thermoforming

Recyclable films having a first layer containing a polyethylene, a second layer containing a high-density polyethylene and a hydrocarbon resin, and a third layer containing a polyethylene may be used for thermoforming packaging components. Both the first and third layers have an overall density between about 0.92 g/cmand 0.97 g/cm. The film structure is advantageous as it can be more easily thermoformed than traditional high-density polyethylene films and can maintain the shape taken during thermoforming, exhibiting minimal warping or shrinking.

The film structure has a first exterior layer having a high-density polyethylene and an inorganic particle, a second exterior layer having a polyethylene-based material for sealing, and an interior layer having a high-density polyethylene, a nucleating agent and a hydrocarbon resin. The film may be use as a heat-sealable lid component for packaging and offers high moisture barrier, good heat resistance, and push-through and/or child-resistance performance while maintaining an overall composition acceptable for recycling.

High performance recyclable lid

A package that is suitable for packaging an article for collecting or administering a pharmaceutical active substance is disclosed. The package includes a first packaging component that includes a product-contacting sealant layer that includes a first ethylene vinyl alcohol copolymer. The package includes a second packaging component that includes a product-contacting sealant layer that includes a second ethylene vinyl alcohol copolymer. The ethylene content of the second ethylene vinyl alcohol copolymer is equal to or less than about 38 percent and the ethylene content of the first ethylene vinyl alcohol copolymer is greater than the ethylene content of the second ethylene vinyl alcohol copolymer.

Product packaging with heat sealable barrier material

The present invention relates to blister components for blister packages formed from multilayer thermoplastic films. In one preferred embodiment of the present invention, the blister component has a layer sequence configuration of A/B/C/B/A. Preferably, layer A is a first exterior layer comprising cyclic olefin copolymer (COC), layer B is an interior layer comprising a high density polyethylene (HDPE), a blend of high density polyethylene, a high density polyethylene nucleation additive and optionally, a hydrocarbon resin (HDPE-Blend), or a bimodal high density polyethylene having a distribution of a low molecular weight region and a high molecular weight region (HDPE-Bimodal), or a high density polyethylene having a thickness of between 38.1 pm to 190.5 pm (1.5 mil to 7.5 mil), layer C is a central core layer. Alternatively, the blister component has a layer sequence configuration of A/B/C/B/D, where layer D is a second exterior layer.
