Many clients throughout the Wellington area have heard the term vacuum forming, but they do not know what it really means, and they don’t know what it does or how it can help them in their business. Vacuum forming is a procedure that can shape performance plastic sheet materials into many different forms, and it is one of the best ways to make a host of different plastic products.
How Does it Work?
A type of thermoforming, vacuum forming, is a process by which a plastic sheet or thin sheet of plastic, such as a PVC sheet, is heated up so that it becomes malleable. The heating process includes the use of aluminum plates and infrared heaters. The heat application will come from the top and the bottom so that it is uniform and will provide the best results.
Once the heat finally reaches the proper temperature (which can differ based on the thickness of the sheets in use) the vacuum will mold the sheets to form the product. The vacuum is able to provide an airtight environment, which is going to be better for the overall molding process.
Products from Vacuum Forming
With this type of thermoforming, one could create countless types of products, and you may find that your company could benefit greatly from the process. One of the most common products using vacuum forming today are children’s plastic toys, but that’s just one of the possibilities. Product packaging is another option, and it is one most companies that create, manufacture, package and sell products could use. Most of the plastic items that you see around the home and office have gone through some type of thermoforming, and it’s often the vacuum process.

We use many products with little to no regard as to how they came to be. One such product is called polystyrene. This is a type of polymer plastic that is used in manufacturing, construction, and for household items that we use everyday. Polystyrene sheets can be molded to specific shapes and sizes and are used in a variety of ways. It can be made into all different types of colors, but is most commonly found to be white or clear.
In manufacturing and construction, polystyrene sheets are used as a packing material. Think of the box your fragile electronics come in. There is usually that hard foam surrounding your purchase, protecting it from bumps and drops, right? This is an insulator formed from expanded polystyrene sheets. In construction, polystyrene sheets are used as molds for concrete or other building materials. They are also used as a form of insulation.
When thinking of it's household uses, you can bet that polystyrene sheets are used in ways that you would never believe! Those little Styrofoam cups we drink from are made from that product. The yogurt you may have eaten for lunch was put into a cup made from it too! Polystyrene is used to make CD and DVD cases, molded to form the handles for disposable razors, and used in many toys that your children may have. It is also a popular product used in many craft materials.
So, why is this stuff so great? For a lot of reasons!
It is lightweight and very easy to work with.
It can be molded into virtually any shape or size, come in large and small sheets or blocks, and can fit easily into a box.
It is a good insulator, protecting objects from water and water vapor, as well as fungus and mildew.
It protects fragile objects from drops, bumps and scratches that may otherwise cause damage.
Polystyrene sheets are available for purchase in many home improvement stores for personal use. You can cut them to the size you need quite easily, or they may be able to cut them at the store, just ask the salesperson if they offer the service. For large quantities used for more commercial purposes, companies on the Internet will be able to fill your order to your exact specifications.
Plastic Sheeting to Prevent Evaporation on Rivers and Water Storage Sources
Plastic corrugated or corrugated plastic as it is commonly referred, is one of the main products used in the reusable packaging industry. Sure, there are other items in this packaging sector such as molded totes or heavy gauge thermoformed plastic trays, but nothing says returnable packaging quite like plastic corrugated. Virtually anything that is made of paper corrugated can be duplicated using corrugated plastic. These items include plastic corrugated boxes, stackable totes, corrugated plastic partitions and dunnage, as well as material handling carts and racks using this resilient material as a main component.
The following tips regarding plastic corrugated will help you think like packaging professional the next time a reusable packaging application crosses your desk.
1. Try different styles of plastic corrugated containers before purchasing a production quantity to make sure you have all of the features your project needs. The best catalog descriptions in the world are no substitute for testing corrugated plastic in real situations.
2. Test different thicknesses of plastic corrugated with your particular application. Corrugated plastic is available in thicknesses ranging from 2mm to 13mm. You may be able to save money by using thinner material.
3. Check to see if your supplier has stock sheets of plastic corrugated from which they can produce your corrugated plastic containers. This will result in a quicker lead time.
4. Compare prices between using a stock sheet of plastic corrugated which is then die cut to your container size and having custom run corrugated plastic sheets for your project. Custom run plastic corrugated sheet sizes should be more efficient for your supplier to run which will result in a lower price per container.
5. Consider applying a printed label instead of direct printing or silk screening on plastic corrugated. Labels on plastic corrugated can look just as nice, will last longer, and cost less than silk screening on corrugated plastic.
6. Ask if a utility or recycled grade of corrugated plastic is available. Utility plastic corrugated is less expensive than virgin material.
7. Evaluate the cost of running a small production run of plastic corrugated (less than 100 pieces) using sample making equipment instead of purchasing a die. There could be a significant price difference.
8. Consider having plastic corrugated partitions and dunnage rod locked so they don't come apart. Corrugated plastic dividers made this way are more stable and last longer.
9. Test plastic corrugated against your product to make sure it doesn't scratch. Plastic corrugated is generally non-abrasive but there are some products that are susceptible to scratching. For these applications use plastic corrugated lined with a non-abrasive coating such as spunbond fabric or even cross link foam.
10. Consider corrugated plastic for internal dunnage that traditionally has been done using wood, steel, or aluminum. Recent advances in plastic corrugated technology allow it to be nailed, screwed, and bolted which results in reusable packaging that is incredibly strong yet lightweight.
In closing, these tips should help the novice as well as the seasoned veteran find alternatives to paper packaging while reducing their cost. In this day and age of pressure for cost reductions, plastic corrugated returnable packaging solutions can help any company improve their bottom line.
