But the need to have a high competitive edge makes farmer look for better alternatives for wood and cardboard. Plastic crates are much easier to handle than wooden crates. Plastic crates supports careful handling because of smooth surface not like the nails and splinters in wooden crates.

With some fruits and vegetable, there is a need for water resistant crate to allow it to keep fresh for longer time. Wooden crates are open and risk drying of the product and Waxing cardboard boxes prevents them from being recycled.

Circulation is necessary in the fruits and vegetable industry. In a vented plastic crates the product can live longer, thus enhances fresh delivery to the market.

Plastic crates are produced by extrusion or injected-moulding methods. The plastic crates are identical to each other and their uniformity is cost effective in stacking on a valuable floor space in a factory, in storage space or a in transportation vehicle space. Plastic crates can be easily stacked to achieve significant saving of valuable space and shipping costs.

In the fruits and vegetable industry, sometimes the pick is loaded into the crates, it stays there. The appearance of the plastic crates are also very attractive and encourages purchases right out of the crate and are cost effective in saving distributing the good into shelves.

The innovative use of folding plastic crate helps Stores compactly when not in use and easily pops open when needed. The folding plastic crate is durable, lightweight, solid and can allows air circulation if needed. The folding plastic crate has easy grip handles and is easily manoeuvred by hand.

The plastic crates are easy to clean with high pressure or washed with water while the wooden crates are subject to bacteria and fungus in present of water.

Plastic crates have high UV resistant, not like wooden crates that are sensitive to changes in temperature.

Many fruits and vegetable companies prefer the use of plastic crates because of their ability to stand freezing conditions while the wooden crates were damaged when freeze. This allows the pick to be shipped in the plastic crates direct into freezers without the need to reload them on a separate container suitable for freezing.

The use of the plastic crates by hand requires steady, durable handles without nails or splinters. This makes the plastic crates better than the cardboard that is lack the durability and better than the wooden crates, that create a safety hazard to personal handling the crate or to product damaged by the nails.

Reuse of plastic crates is cost effective in purchasing costs. It eliminates endless purchases of cardboards that have a very short life span, and the need to buy wooden crates that have a higher life span but still 15 times less than the plastic crate. The empty plastic crates are nested within each other, which means they occupy less space and reduce shipping weight, providing savings in return distribution. The choice of reusable plastic crates or disposable cardboard boxes to transport perishable goods is often determined by the purchase price of the containers. But this is deceptive: When related overheads such as packing, shipping and storage are included, the actual cost can be up to four times as high.

Returnable Plastic Crates offer: real packaging material cost savings, more efficient unit loads, better use of precious warehouse space, increase profit and improve customer satisfaction all along the supply chain.

Reuse of plastic crates, contributes to prevention of global warming by reducing the use of trees for wooden boxes or the making of cardboard boxes.

The use of plastic crates is the most efficient and effective way of getting your products to market.

Plastic crates are used to store and move goods through all links of the distribution chain.

Plastic Crates are usually loaded in the first segment of the material handling process, and then stored or are shipped to a new location.

Plastic crates help protect delicate and fragile products, like produce, from the field through the warehouse or distribution centre, all the way until they reach the merchant’s shelves.

The use of plastic crates provides smooth, protective handling, good stability and excellent ventilation if needed.

In the grocery industry, Returnable Plastic Crates, commonly called RPC’s, which are rigid for outbound trips and folding for inbound trips, are now being used to transport all types of produce between growers and supermarkets all over the world. With one common footprint and six different stack heights that conform to the different produce, these plastic crates can be mixed on pallets to make more stable and efficient unit loads.

Reusing plastic crates is preferable to recycling as it uses less energy and fewer resources. Long life, multi-trip plastics packaging has become more widespread in recent years, replacing less durable and single-trip alternatives, so reducing waste. For example, in the UK alone, the major supermarkets have increased their use of returnable plastic crates for transport and display purposes four-fold from 8.5 million in 1992 to an estimated 35.8 million in 2002. Plastic crates last up to 20 years and can be recycled at the end of their useful life.

Reduced packaging waste is not the only benefit of using RPC’s instead of corrugated boxes, wooden flats, or foam polystyrene for produce. Better protection and reduced chilling time means more produce gets to market quicker and fresher than ever before. Sturdier transport packaging means fewer collapsed loads from moisture-saturated cardboard. The use of plastic crates is efficient in reducing warehouse space because they can be stacked or folded on top of each other without fear of damaging their precious unit loads.

Standard wooden crates are used for all grocery products that are not sensitive to weather or water. They cannot be used for dairy, health, beauty aids, automated meat systems or frozen food storage.

Plastic crates used in distribution and storage industries are an advanced reproduction of the traditional wooden crates.

The use of plastic crates has also increased because of awareness of global warming. Their reusable quality and recycling possibility, makes them the best option in the market today.

Plastic containers have no sharp edges, no nails and no splinters. Using plastic crates lessens insurance costs associated with workers’ injuries and damage to goods.

Space savings

Plastic crates are space saving relatively to wooden crates and therefore decrease shipping and storage costs.

Plastic crates in contrast to the wooden products can be easily stacked on top of each other even outside in all weather conditions and save storage space.

A stack of ready-to-go nested Plastic crates will use less than half the space of a similar number of wooden crates. Nesting allows distribution centres to have a supply of products on hand ready for shipment.

Nestable or folding plastic crates are cheaper to transport when empty – 24% to 60% less space and weight.

Ease of use

Plastic crates are easier to handle than wooden products because of uniformity, variety of design and ease of manoeuvrability.

Uniformity of plastic crates on factory assembly lines causes fewer stoppages by size differences. Plastic crates are moulded. They are 100% identical to one another in size and allow easy calculation of measurement for shipping and storage. They are also easy to use with robots and assembly lines.

Plastic crates offer a wider variety of designs than wooden products. There are over 15.000 k kinds of crates to suit different needs, sizes and load requirements.

Plastic crates offer easy handling by hand because of durable handles.

Plastic crates are lighter than wooden crates. Therefore, Plastic crates have an advantage in manoeuvring by human hand.

Versatility

Plastic crates are more versatile than wooden crates.

Plastic crates can be used in cold and warm conditions from -22℃ to +60℃ (-40℉ to +140℉) with no damage, unlike wooden crates, which are damaged by even mild changes in temperature.

Plastic crates have a very high UV rate. They can be stored outside in rain, wind and sun, which have little to no damaging effect. Wooden crates are sensitive to the elements.

Ease of Cleaning

Plastic crates are much more hygienic than wooden crates. The hygienic properties of plastic crates are extremely important in agriculture, food and pharmaceutical industries.

Plastic crates are easy to clean with solvents, steam or water, while wooden crates are damaged in contact with solvents, steam and water. Plastic crates can be steam-cleaned with temperatures up to 120℃.

Plastic crates are not a substrate for bacteria, fungus and insect contamination, unlike wooden crates.

Plastic crates do not absorb water and are impervious to acids, fats and solvents, while wooden crates are most sensitive to acids, fats and solvents.

Durability

Due to their strength and design, plastic crates are more durable than wooden crates. The average plastic crate’s life ranges from 50 to 500 usages (depending on its type) versus 10 to 50 usages for the wooden products which then need to be repaired. That’s about ten times more durable.

Cost Efficiency

Plastic crates are much more cost-effective relative to wooden crates because of their durability. The cost of a plastic crate ranges from as low as US$2.00 up to US$60.00 with the average price about US$17. The average cost of a wooden product is about US$9. However, on a per-trip basis plastic crates are by far more cost-effective than wooden crates. The average cost per trip is about US$0.01 for a plastic crates, compared with an average of US$0.25 per trip for the wooden product.

There are other costs associated with continually purchasing wooden crates and maintaining them as opposed to plastic crates. There are also costs associated with warehousing because of damage to shipped product due to broken wooden crates or damage caused by nails or splinters. Plastic crates are durable and save cost on insurance on returned products.

Plastic crates are significantly lighter than wooden crates. Plastic crates weigh 2-4 times less than wooden crates. The lower weight of plastic crates results in savings of shipping costs, especially for air freight.

Plastic Crates Manufacturing Process

Plastic injection moulding machine

Plastic Crate Manufacturing Plastic crates have an advantage because they can be manufactured using several different technologies: high impact injection moulding, structural foam injection moulding, blow moulding, rotational moulding, single-sheet vacuum thermoforming and twin-sheet thermoforming.

The High Impact Injection Moulding process involves forcing a hot mixture of resin into a mould to make a plastic crate. Plastic crates made by the injection moulding process have many internal features such as channels and ribs to increase the strength of the crate and reduce its weight. The finished product is a solid plastic crate that is very rigid and sometimes too fragile for some applications. Injection-moulded crates have lower impact strength relative to other types of plastic crates, particularly at low temperatures.

Structural Foam Injection Moulding is similar to conventional injection moulding, except that a foaming agent is introduced with the resin melt and injected into the mould using low pressure. The result is a crate, with an integral skin and, a cellular foam core with a high strength-to-weight ratio. An advantage of structural foam is that it gives the crate some flexibility. This process also helps to keep the overall weight and material costs of this plastic crate down. This kind of plastic crate is consistent and offers good dimensional stability. It can be manufactured with post-consumer recycled material to reduce the cost. Structural foam plastic have the highest load capacity among different types of Plastic crates. They are particularly useful for heavy-duty applications.

Blow Moulding involves injecting air into the mould to blow the plastic out to the sides of the mould. The resulting crate looks like a twin-sheet thermoformed crate. Blow moulded Plastic crate have lower structural strength than other types of crates and can be used for light-weight products.

Rotational Moulding uses a large, clamshell-like mould loaded with resin in granular form. The mould spins over a heat source and the centrifugal force pushes the melted resin to the sides of the mould, creating the Plastic crate. Rotational moulding principal has an advantage because of its lower-cost tooling. However, the process is more time-consuming than others. It is not the process to use for high-volume, specialized requirements.

Vacuum Thermoforming involves a sheet of plastic that is pulled onto a mould via a vacuum process. This is one of the lower-cost methods for making Plastic crates. Tooling for vacuum forming and twin-sheet thermoforming is less expensive than for injection moulding or structural foam moulding. However, vacuum-formed crates tend to have rather thin walls, offering limited impact strength. Some manufacturers add steel rods within the plastic shell to give the crate strength.

Twin-sheet Thermoforming is similar to vacuum forming, except that two sheets of plastic are brought together. In twin-sheet thermoforming, two sheets are pulled into-the mould at the same time. The two sheets are bonded together with heat. The twin-sheet plastic crates are durable, often showing little if any damage after being hit .The disadvantage of the twin-sheet thermoformed crate is their lower dynamic load capacity comparatively to structural foam crates.

Among all of the types of plastic crates available on the market, structural crates are considered the best for major heavy-duty closed-loop applications in food distribution for storage and delivery systems.
