C-Type

C-type design is based on the Japanese "Bento" lunch box
with removable plate lid attachment. Corrugated plastic
cannot be folded as with A-type, but
is extremely durable with reinforced bottom.

  • Lunch box type

    Lunch box type

    In the style of Japanese "Bento" lunch boxes, the lid and box separate completely. Double-ply sidewalls for extra strength.

Corrugated plastic

Corrugated plastic

Corrugated plastic is molded from a hollow polypropylene sheets.

The polypropylene construction is extremely heat, water and chemical resistant, and easy to produce.
Sleek and eye-pleasing, popular for use in advertising boards and displays.
Light and hollow design, high pressure and shock resistance, and low cost production have also made this product popular as construction safety sheeting and curing sheets.
A functional, rational, and economical trend-setting new product.

About recycling

Corrugated plastic has high fluidity, and can be melted down and easily recycled after its lifespan is finished.
The pulverized pellets of the recycled materials are used to make factory pallets, and other familiar goods such as garbage bins and polyethylene buckets.
Cut-up and scrapped corrugated plastic is recycled into a multitude of new plastic products. Aside from being used as resin in factory pallets, it is also used in fuels.

An environmentally friendly product

CO2 emission graph / CO2 emissions (kg) / Corrugated plastic / Corrugated cardboard box / Volume  (individual)

The amount of CO2 emission for the production of a 40x40x40 cm cubic A-type corrugated cardboard box is about 0.5 kg for each.
The amount of CO2 emission for a same-sized A-type corrugated plastic (Orange crate type) is about 5 kg.
However, if a disposable corrugated cardboard box, which is only meant to be used once, could be used ten times over, each use would constitute a reduction in CO2 emission, making it a "green" product.

Features of hollow design

Lightweight

Heat Insulated

Heat Insulated

Compared to solid-form plastic, the hollow form is lightweight Sound reverberation is reflected and absorbed in the ribbing, making it an excellent sound suppressor. Ribbing decentralizes impact shocks, making for excellent shock cushioning. Low thermal conductivity on the PP due to a lair of air which makes heat conducting difficult.

Features of polypropylene

Water resistant

Water resistant

Easy to manufacture as desired by cutting, punching, bending and bonding. Excellent against alkaline, acids and solvents. Does not wear and tear like paper-based material, strong and durable. Absorbs almost no moisture (0.03%), getting it wet does not cause any problems.

High functionality

High functionality

Does not attract static dust due to natural resistance to static electricity. Handles corona static discharge well enough for silk screening. A higher anti-slip grade than corrugated cardboard. Various different materials can be attached to create an assortment of highly functional sheets.

Cost merits

The cost of boxes is becoming cheaper

Box expense graph

Continuous use (running cost) graph

The cost of each box becomes higher than corrugated cardboard boxes.
However, corrugated plastic differs from corrugated cardboard boxes in that as a strong box which can be reused roughly ten times over again, the running costs are ultimately cheaper than cardboard. If used conservatively, corrugated plastic boxes can be reused more than 30 times.

Reduce hidden costs

Cost graph / Disposal costs / Maintenance costs /Ordering costs / Sealing costs / Box costs

In considering distribution prices, there are many other costs to consider beyond just the box itself.

Sealing costs Costs for box sealing and the required processing and tools. In the case of corrugated plastic, sealing can be done simply with tape.
Ordering costs Ordering costs comprise a high amount of the hidden costs. Orders that can’t be filled due to insufficient stocks, creation of order forms, and other order processing costs can mount up.
Maintenance costs Corrugated cardboard packaging is often sold in set lot amounts, requiring extra management for excess boxes in an order. Space for excess lot boxes also has to be alloted and managed.
Disposal costs Waste collection for disposable items also inters costs.

Yearly supply and distribution costs for heavy-duty corrugated plastic boxes are far cheaper than those of corrugated cardboard.

Functional merits

Dust-free

Manufacturing of corrugated cardboard boxes, and cutting of corrugated cardboard sheets, creates excess dust. This dust clings to the boxes and often mixes in with the packaged goods, making cardboard useless for industrial packaging of perishable foods, medicinal supplies and precision engineered devices. Also, many factories have adopted sterile clean rooms in recent, and cardboard packaging is typically not allowed in these rooms.
The custom design of corrugated plastic safeguards against contamination from foreign elements.

Protection from static electricity

Protection from static electricity is indispensable in nearly every field of manufacturing. Static electricity attracts dusts and causes ESD damage, waging negative effects on the packaged goods. Heavy duty corrugated plastic boxes are constructed from conductive plastic sheets that negate static electricity.

Water resistant

Corrugated cardboard boxes quickly degrade and become tattered when exposed to water.
Heavy duty corrugated plastic boxes are built to be water resistant and do not degrade with water exposure.
However, water trapped inside the box does pose a risk of mold, so please be sure to avoid water exposure and wipe the surface thoroughly.

Environmental merits

An environmentally friendly product

The amount of CO2 emission for the production of a 40x40x40 cm cubic A-type corrugated cardboard box is about 0.5 kg for each.
The amount of CO2 emission for a same-sized A-type corrugated plastic (Orange crate type) is about 5 kg. However, if a disposable corrugated cardboard box, which is only meant to be used once, could be used ten times over, each use would constitute a reduction in CO2 emission, making it a "green" product.

Re-usability & raw materials

Corrugated plastic has high fluidity and can be melted down and easily recycled after its lifespan is finished.
Cut-up and scrapped corrugated plastic is recycled into a multitude of new plastic products. Aside from being used as resin for factory-use pallets, it is also used to produce fuels.
