Package profile formation through extrusion presents significant material flow and thermal management challenges. Traditional extrusion processes operating at 150-200°C can lead to irregular wall thickness, surface defects, and thermal degradation—particularly when processing temperature-sensitive materials like biodegradable polymers or composite laminates.

The fundamental challenge lies in maintaining precise material flow characteristics while managing the competing demands of throughput speed, thermal stability, and final product integrity.

This page brings together solutions from recent research—including dual polymer configurations with adjustable friction coefficients, integrated cooling and lubrication systems, and pressure-adaptive control mechanisms. These and other approaches focus on achieving consistent profile formation while optimizing material properties and processing efficiency.

1. Packaging Assembly with Duct-Integrated Water Distribution for Lubrication and Cooling of Sterile Tubes

テトラ ラバル ホールディングス アンド ファイナンス エス エイ, TETRA LAVAL HOLDINGS AND FINANCE SA, 2024

Packaging assembly for forming and sealing pourable product containers using sterile tubes of packaging material. The assembly reduces water consumption, improves lubrication and cooling effectiveness, extends component life, and improves package quality compared to conventional assemblies. The assembly has a duct around the tube upstream of the forming and sealing jaws. Water is forced through holes in the duct to lubricate and cool the tube as it passes. This reduces friction during forming and prevents overheating during sealing.

2. Press-Through Packaging Sheet Comprising Vinyl Chloride Resin, Biomass Resin, and Epoxidized Vegetable Oil with Specified Storage Modulus

MITSUBISHI CHEMICAL CORP, 三菱ケミカル株式会社, 2024

Sheet for press-through packaging, like for medicine blisters, with improved properties for environmental friendliness and manufacturing ease. The sheet contains vinyl chloride resin, biomass resin, and a plasticizer. It has a specific storage modulus range of 1-2.6 GPa at 30°C. The biomass resin is a butylene succinate like polybutylene succinate. The plasticizer is epoxidized vegetable oil like epoxidized soybean oil. The vinyl chloride resin has low chlorine content. This composition allows manufacturing press-through packages with biomass content over 10% and reduced bleeding of plasticizers during production.

3. Device for Compressing and Packaging Livestock Manure Compost with V-Shaped Receiving Chamber and Integrated Moisture Management

11. Method for Manufacturing Paper Packaging with Pretensioned Recess Formation Using Clamping Jaws and Tension Rollers

SYNTEGON TECHNOLOGY GMBH, シンテゴンテクノロジー ゲー・エム・ベー・ハー, 2024

Method to manufacture paper packaging with recessed areas for containing items, that reduces wrinkles and microcracks compared to conventional methods. The process involves pretensioning the paper web material before forming the recesses. This prevents wrinkles and allows reliable shaping without excessive stress. The pretensioning step uses clamping jaws and tension rollers to tighten the paper in both directions. The forming step uses a die, hold-downs, and pneumatic pressure to mold the paper into the recesses. The hold-downs are moved to feed the paper during forming to prevent wrinkles. After forming, the recessed packaging is removed from the die. This two-stage shaping process prevents tearing and reduces wrinkles compared to direct molding.

12. Blister Packaging Machine with Anti-Stick Die-Cut Punch and Conveyor System

CKD CORP, 日商CKD股份有限公司, 2024

Bubble packaging machine for manufacturing blister sheets containing pills. The machine has a mechanism to prevent the blister membrane from getting stuck on the die-cut punch during sheet production. It involves a specially designed conveyor system that guides the blister membrane through a series of rollers and guides to smoothly and reliably transport it without loosening or catching on the punch. This prevents the membrane from sticking to the punch as it punches out the blisters, reducing the risk of jamming and improves production efficiency.

13. Polyolefin Sheet with High-Density Polyethylene and Crystal Nucleating Agent for Enhanced Divisibility and Transparency

MITSUBISHI CHEMICAL CORP, 三菱ケミカル株式会社, 2024

Packaging design with fiber-based materials that allows steep flanks and fixation features for securing packaged goods. The packaging has two elements, one with a cavity and the other with a contour, that fit together to enclose items. The cavity element is formed by deep drawing fiber material to create a recess for the goods. The contour element is also formed by deep drawing to create a feature that extends towards the cavity element to fix the goods inside. This allows fiber-based packaging with steeper flanks and fixation features for securing packaged goods, improving stability and preventing goods from moving or prying open the packaging.

15. Rotary Punching Device with Detachable Punch Bars for Continuous Operation in Packaging Machines

CHO WHI DO, 2023

Punching device for packaging machines that allows efficient punching of hanging holes in sealed packaging material without stopping the machine. The punching device has detachable punch bars that can be easily replaced if worn or malfunction instead of replacing the whole device. The punch bars attach to rotating parts of the device that move up and down as the packaging material passes through. This allows the punch bars to be raised and lowered with the material instead of relying on external force to lift the punches. This enables punching the hanging holes while the machine is running without stopping. The detachable punch bars also allow customization of punch size and shape for different packaging materials.

16. Manufacturing Method for Lidding Sheet with Adjustable Resin Coating and Scratch-Enhanced Base Layer
