PLASTICS IN THE FOOD & BEVERAGE

Plastics: The Secret Ingredient in the Food & Beverage Industry

Cutting Boards

In both industrial and home settings, cutting boards are indispensable for food preparation. While wood and glass have their merits, plastics like Polyethylene offer a superior combination of durability and hygiene. They are less porous than wood, making them less susceptible to bacterial growth, and unlike glass, they are less likely to dull your knives.

Key Components Made of Plastics

The versatility of plastics allows them to be used in a wide range of components within food and beverage machinery. Let's delve into some of these:

  • Cutting Boards: Plastic cutting boards are durable and low-maintenance. They are less porous than wooden ones, offering better resistance to bacteria and they do not blunt knives as glass boards can.
  • Bushings and Bearings: These reduce friction between moving parts, and plastics like Nylon are often preferred due to their self-lubricating properties.
  • Conveyor Parts: From belts to rollers, plastics offer a lightweight yet durable solution, facilitating the smooth transportation of products along the assembly line.
  • Feed Screws: Used in machines that handle granular materials like sugar or grain, plastic feed screws are less prone to wear and are easier to clean.
  • Guide Rails: These components guide the movement of products through the machine, and plastics offer the advantage of reduced friction and noise.
  • Machine Guards and Windows: Safety is paramount, and clear plastics like Polycarbonate are used for machine guards and windows, allowing operators to safely monitor the process.
  • Pipes and Tubes for Fluid Processing: As mentioned earlier, plastics like PVC and HDPE are ideal for fluid handling due to their corrosion resistance.
  • Pistons and Plungers: Used in pumps and valves, plastics offer the benefit of tight seals, minimizing leaks.
  • Seals, Seats, and Gaskets: These components ensure that machines are airtight and leak-proof. Materials like Polyetheretherketone (PEEK) are often used due to their excellent chemical resistance.

Advantages of Using Plastics

  • Lightweight for High-Speed Production
    • The lighter the components, the faster a machine can operate. This is especially crucial in an industry where production volumes can be enormous. Plastics facilitate high-speed operations by allowing the use of smaller drive motors, thus saving on energy costs.
  • Reduced Maintenance and Contamination
    • The absence of corrosion and the reduced wear and tear on plastic components translate to lower maintenance costs. Moreover, many plastics are self-lubricating, eliminating the need for additional lubricants that could contaminate the food products.
  • Resistance to Cleaning Chemicals
    • In an industry that demands the highest hygiene standards, the ability to withstand aggressive cleaning agents is a significant advantage. Plastics like Polypropylene and Polyethylene Terephthalate (PET) are known for their chemical resistance, making them ideal for components that come in contact with cleaning solutions.
  • Long Wear Life
    • Given their resistance to wear and tear, plastic components often outlast those made of other materials. This long wear life means fewer disruptions due to maintenance and replacements, ultimately leading to cost savings.

Compliance with Regulations

Safety is a non-negotiable aspect of the food and beverage industry. The use of plastics that comply with FDA, NSF, and other regulatory standards ensures that consumer health is not compromised.

Types of Plastics Commonly Used

The choice of plastic material depends on various factors such as temperature resistance, chemical exposure, and mechanical stress. Here are some commonly used plastics in the food and beverage industry:

  • Acetal (POM): Known for its high strength and stiffness, Acetal is commonly used in gears and bearings.
  • Acrylic (PMMA): This plastic is often used for transparent components like machine guards and windows due to its excellent clarity and light transmission.
  • High-Density Polyethylene (HDPE): Ideal for cutting boards and containers, HDPE is known for its durability and chemical resistance.
  • Nylon (PA): Used in a variety of applications, from bushings to conveyor belts, Nylon offers excellent wear resistance.
  • Polycarbonate (PC): This material is used for transparent components that require high impact resistance.
  • Polyethylene Terephthalate (PET): Commonly used in food packaging, PET is known for its excellent moisture and chemical resistance.
  • Polyetheretherketone (PEEK): This high-performance plastic is used in seals and bearings due to its excellent mechanical properties and chemical resistance.
  • Polyetherimide (PEI): Known for its high-temperature resistance, PEI is used in applications where sterilization is required.

Our Capabilities

  • CNC Routing: This method allows for high-precision shaping of most plastic materials, including complex geometries.
  • Laser Cutting and Polishing: Lasers offer a one-step solution for cutting and polishing edges, providing a high-quality finish.
  • Acrylic Etching and Engraving: This technique is used for adding text or designs, commonly seen in signage or machine labels.
  • Heat Bending: This allows for the creation of curves and angles in materials like acrylic and polycarbonate, often used in machine guards and displays.
  • Sanding, Beveling, Polishing, Drilling: These finishing techniques add the final touches, ensuring that the components meet the required specifications.
