Wrap The Pallet Without Sealing In The Heat

Jiamei has manufactured perforated stretch film and knitted pallet netting since 1987. Thirteen holes in every row keep warm and damp loads cooling and drying inside the wrap, so cartons stay dry, labels stay readable and the cold chain keeps its schedule.

What We Make

Perforated ventilated stretch film in prestretchable and already prestretched grades, knitted pallet netting in rigid HDPE and elastic MPE, and bale netwraps. All of it produced at our own factory in Ruian, Zhejiang.

Who We Serve

Agricultural and industrial packers who wrap goods that are still warm or damp: breweries, soft drinks, pasteurised goods, canned foods, pharmacies, dairy, fruit and vegetable, plants, meat, fish and frozen snacks.

What Problem We Solve

A sealed wrap traps heat and moisture against the goods. Cartons soften, labels lift, cans mark and the cooling cycle runs long. A perforated wrap holds the load and lets the pallet keep breathing.

Why Buy From Us

Thirty eight years of making one narrow category of packaging, published tolerances on every technical figure, rolls customised to your wrapper, and a factory close to Wenzhou airport and Ningbo port.

Two Ways To Hold A Pallet And Still Let It Breathe

Film gives you a smooth protective surface with thirteen open holes in every row. Netting gives you a continuous open mesh that grips irregular loads. Most sites end up using both.

Why A Perforated Wrap Changes What Happens Inside The Pallet

Warm goods release moisture. Under a solid film that vapour has nowhere to go, so it condenses on the coldest surface it can find, which is usually your cartons. Thirteen holes in every row give it a way out.

Frequently Asked Questions

What does Jiamei manufacture

Jiamei is a manufacturer of plastic packaging established in 1987. We produce ventilated stretch film, bale netwraps and pallet nets for agricultural and industrial packaging, from our factory in Ruian, Zhejiang Province.

What is ventilated stretch film used for

It is a perforated stretch film designed to maximise the aeration of the product wrapped. The open structure allows quicker cooling and drying of palletised goods, which matters wherever condensation or moisture builds up under a normal wrap.

Which industries use these products

Breweries, soft drinks, pasteurised goods, canned foods, pharmacies, dairy, fruit and vegetable, plants, meat, fish and frozen snacks. Anywhere a pallet is wrapped while it is still warm or damp.

Can film and netting be customised

Yes. Ventilated stretch film and pallet nets can both be customised to your request, including roll length, web width and inner core diameter. Send your wrapper model and pallet size and we will confirm what we can produce.

Do you supply rolls for hand wrapping as well as machines

Yes. Ventilated stretch film is available in machine rolls and manual rolls, and pallet netting is available for both manual and automatic use, with manual rolls of 500 to 1000 m and automatic rolls of 3000 to 4000 m.

Where is the factory and how do goods ship

The factory is in Qianbei Industrial Park, Baotian Village, Tangxia Town, Ruian City, Zhejiang Province, close to Wenzhou airport and Ningbo port.

How do I get a quotation

Message us on WhatsApp or send an email with your pallet size, load weight, wrapping equipment and the temperature at which goods are wrapped. Those four details are usually enough for us to recommend a grade and quote.
