A multi-layer film comprising, an outer two layers of the multi-layer film comprising a linear low density polyethylene (LLDPE) butene resin, a next two inwardly successive layers of the multi-layer film comprising a linear low density polyethylene (LLDPE) hexene resin, wherein at least one of the next two inwardly successive layers comprises one or more recycled resin components, wherein at least one of the one or more recycled resin components are filtered using continuous filtration, a core layer of the multi-layer film comprising a linear low density polyethylene (LLDPE) hexene resin, and at least one edge of the multi-layer film comprising a folded edge.

Woven irrigation tubing comprises a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.

A transparent thermoformed high barrier plastic bottle is provided for use in storing food and beverages, personal care products, health care products, and other applications that require excellent transparency and barrier properties. The transparent thermoformed high barrier plastic bottle includes first and second outer layers formed using a transparent polyester or polyester copolymer; an inner nanolayer sequence including a plurality of nanolayers a) including ethylene vinyl alcohol, alternating with nanolayers b) including at least one of ethylene ethyl acrylate, low density polyethylene and linear low density polyethylene, each of the nanolayers b) having a degree of crystallinity less than about 45%; and adhesive layers between each of the two outer layers and the inner nanolayer sequence. A method for producing a transparent thermoformed high barrier plastic bottle is also provided.

This invention provides a food container which can be manufactured cheaply by using inexpensive general PET resin or further inexpensive PET resin for fiber or recovered PET flakes, and nevertheless, which has a high heat resistance up to 250° C., and the container is obtained by adding a chain extender and a compatibilizer and talc to PET resin, charging the mixture into an extruder 30 having two or more vent holes, degassing under a condition where the PET resin is melted with heating by sucking at a high vacuum of −99.99 kPa or lower from the vent holes 33, 34, thereafter, forming a sheet by extrusion molding, pressure-forming with vacuum the sheet by a thermoforming machine, forming the container by keeping in a mold at 100-220° C. The container has a total of the content of crystal portion represented by the following formula and the content of talc being 25% by weight or more.

A moisture barrier layer-foamed polymeric composite sheet underlayment article comprising a foamed polymeric sheet and a moisture barrier layer adhered thereto is disclosed. In one aspect, cork particles are present in the composite.

The resin composition of the present invention comprises 40 to 98 parts by mass of a modified starch (A), 2 to 60 parts by mass of a polyvinyl alcohol (B) having a degree of saponification of 75.0 mol% or more, and optionally a clay (C), wherein the total content of the (A), (B) and (C) is 100 parts by mass, and the peak temperature of tan δ in measurement of dynamic viscoelasticity in a range of 20° C. to 150° C. is 128° C. or lower.

The smoothing device for plastic films comprises plastic-melt-producing means (1, 5), an adjustable slit die (10) and a roller smoothing unit (16) having cooled smoothing rollers (11, 12), which form an adjustable smoothing gap (13) between each other. Optionally, further rollers (15) are arranged downstream. A thickness gauge (23) measures the thickness of the plastic-film web (22). A controller (30) for controlling the thickness of the plastic-film web (22) may set a setpoint thickness (SD) of the plastic-film web (22) and the volumetric flow rate (SS) of the plastic melt or the line speed (LS). The controller (30) captures the current torques and rotational speeds of the rollers (11, 12, 15) and the current thickness (FD, FD1-FDn) of the plastic-film web (22).

The controller (30) sends setpoint rotational speed signals (C0S, C2S-CnS, CAS) calculated from the captured torques of the rollers (11, 12, 15) to the drives of the rollers and a smoothing-gap setpoint distance signal (GW) for adjusting the smoothing gap (13), and furthermore—in the case of a specified line speed (LS)—setpoint plastic-melt volumetric flow rate signals (SS) to the plastic-melt-producing means, or—in the case of a specified plastic-melt volumetric flow rate (SS)—setpoint line speed signals (LS) to the drives of the rollers (12).

An apparatus, a system, and a method for improvements in fused filament fabrication (FFF). Characteristics of a filament may be measured during production of the filament and the characteristics stored in a memory for retrieval by a 3D printer. The 3D printer adjusts print settings as necessary based on the measured characteristics, thereby resulting in better print quality.
