What is PP moulded crate packaging solution?

Plastic crates are containers used for moving or transporting goods from point A to point B. They are also used for storage and are made of exclusively or partially plastic material. The basic material is plastic; it gives its distinctive character of durability. They are more expensive than wooden or carton crates due to their durability lasting or having a longer life span compared to other crates.

Orientations and Types of Plastic Crates:

  • Collapsible Plastic Crates
  • Non collapsible Stacking Crates
  • Stack-Nest Crates
  • Stack-Nest Crate With Swing Bars

The introduction of plastic crates has eliminated many problems associated with storing goods in wooden crates and cardboard crates. Plastic crates are accessible in varying sizes and shapes, and each of them has its distinguished applications and specifications. Customers or clients have the option to determine the quality of the crate according to their usage program.

Plastic crates can be found in different orientations and types.

Orientations of Plastic Crates.

Plastic crates have different stacking orientations, including a stack-nest, a stacking, or a collapsible design. The differences are particularly important when the crate is transported empty since the volume determines the price to be paid for transport.

Collapsible Plastic Crates

These are the most expensive crates to purchase followed by stack-nest plastic crates and then the stacking crates.

Non Collapsible Stacking Crates

They are designed as square and they contain rounded corners, an efficient use of available space is possible as they can be stacked one on top of the other. Depending on the size of the crate, the loss of loading space compared with loose break bulk is much better than stacking.

Although stacking crates have a rigid design, some space during the return trip can be obtained by putting one crate inside two others and overlapping crates during stacking. Some space gaps in the crate's rim are needed, making transportation after delivery also easier.

Stack-Nest Crates

The stack-nest crates can be found with swing bars or with a cover or be stacked at 180°.

Stack-Nest Crate With Swing Bars

The volume of the inside of a stack-nest crate is less than the inside volume of a crate with a squared design because of its vertically tapered shape. Effective loading space is higher depending on the size of the crate. Five nested crates will use up the space occupied by two stacked crates of similar size with the swing bar design. The crates can be nested if the bars are swung out. A swing bar is swung from the outside or the side over the top of the crate, forming a support for the following crate.

Types of Plastic Crates

Regular Plastic Crates

These are used for all kinds of basic storage conditions. They are accessible in many various shapes, colors, and sizes. These include plastic crates for grocery distribution. They help by protecting fragile and delicate products such as produce. The use of these crates brings smooth, protective handling, excellent ventilation, and good stability. In the grocery industry, there are what are called returnable plastic crates which are folding for inbound trips and rigid for outbound trips used to transport all types of produce between growers and supermarkets around the world. These plastic crates have one common footprint and six different stack heights conforming to the different products and can be mixed on pallets to make the unit loads more stable and efficient.

Ventilated Plastic Crates

These are normally used for the storage of food items and vegetables. They are accessible in a fully ventilated and nestable design. These include plastic crates used in the dairy industry. They are made from a material called polyethylene which is strong and resilient. There are also plastic crates that are custom-made, which can be made use of from the beginning to the final stage of the process of handling the materials. They can be used for farmers to display on the shelves of supermarkets and then to the customer and therefore finally their kitchens.

Closed Plastic Crates

These are high-quality closed crates that can be made in various sizes and shapes. Generally, they are used for all types of storage, including fish in the fishing industry and other food items. These include plastic crates for the fishing industry. The plastic crates are used in the transfer of the catch to the company's holding tank, where they are processed. Seafood processors and wholesalers mostly use these crates.

These plastic crates are better than wooden ones in the fish industry because their handling is much easier. Plastic crates support careful handling due to their smooth surface, unlike the nails and splinters found in wooden crates. Their opening is also easier as well as their closing than wooden crates that have craftsmanship that is not accurate.

6040 Plastic Crates

These crates are designed and made for multiple purposes in 600L and 400 W dimensions.

Jumbo Plastic Crates

These are big-sized crates which are mainly utilized in the storage and transportation of large items.

Applications and Benefits of Plastic Crates

Crates in the Dairy Industry

In the dairy industry, milk crates serve as an extremely important means to supply milk cans and packets across cities and towns. They are also important and efficient in shipping milk across long distances, holding them firmly and avoiding spillage. While compared to wooden and cardboard crates used in the prior years, plastic crates have now become an increasingly gained market due to their lightweight and resilient structures. Typically made of polyethylene (PE), plastic milk crates are resistant to repeated washing and ensure more hygiene in the supply process.

Agriculture Uses

Plastic crates are important and play a very important role in the agriculture industry, facilitating a hygienic and efficient transportation process. These are suitable alternatives to the other ones such as traditional wooden and cardboard counterparts as plastic crates resist the growth of fungi within them. As a result, plastic bins and crates are gaining popularity in the market and are chosen for the transport of agricultural produce, soil, and seeds on a large scale. Moreover, plastic crates are also resistant to extreme weather conditions, which aids in the secure transportation of perishable agricultural products in the industry. The nature of the products to be transported in the agro-industry requires extra care to be taken in terms of hygiene and proper maintenance. Plastic allows for increased efficiency as an element in the supply and transportation of such products.

Fishing Industry

Fisheries utilize plastic crates and also plastic fish tubs and ice boxes to prevent fish from perishing while being transported. As a poor conductor of heat and resistant to rain, heat, and other harsh weather conditions, closed plastic crates protect the ice within the crates and containers from melting and ensure that the fish stored within remains fresh even after being transported across long distances. Moreover, cleaning plastic crates can also be done for hygiene. This can be more easily done compared to crates made from other materials. Thus, even in case of spillage, these may be cleaned more easily and hygienically maintained. In this industry, rust is not allowed.


Benefits of Plastic Crates

  • They are strong, rigid crates that can be used for many journeys, making the cost per journey relatively low.
  • Different sizes and shapes can be made available according to the customer’s specifications.
  • The plastic crates are easy to clean and disinfect after use.
  • Plastic crates are strong and have good weather resistance. (This enables the crates to be used in humid areas and during hydro-cooling).


Auto Industry

  • The auto component manufacturer as well as OEMs utilize plastic crates for in-house storage of components as well as material movement within plant premises from the plant warehouse or storage area to the production and assembly line.
  • Auto components manufacturers also use these crates for the supply of components from their plants to nearby end customers or OEM manufacturing plants.


Vegetables and Fruits

  • Transporting fruits and vegetables across long distances requires special care and hygiene to be practiced as these are perishable and easily affected by harsh weather conditions. Plastic crates are popular options for transporting such goods because they are compact and resist external deterrents.
  • A variety of fruits and vegetables are transported every day, in plastic crates, from one place to another. In fruit and vegetable transportation, the storage of these crates may be done in in-built systems of pallet storage, before they are further transported to the markets.
