When it comes to the production of aluminum foil trays, one of the most important choices you would need to make is choosing the right temper for the manufacturing process that uses jumbo roll of aluminum foil made using alloy 3003.
Aluminum foil of 3003 grade contains 1.0 - 1.5% manganese and is strongly associated with metalworking characteristics that allow it to create heavy duty food containers.
However, many customers across the globe get puzzled about temper H22 versus H24.
Making the wrong choice of temper for the alloy might result in high rejection rate, deformation of trays, cracking of edges and rising material costs.
Both the H22 and H24 semi-hard tempers can be classified as partially annealed temper, and yet they differ substantially in their yield strength and elongation features.
H22 boasts higher ductility and moderate strength making it perfect for deep-drawing purposes whereas H24 has superior hardness and rigidity but a bit lower elongation rate and can serve shallow-drawn tray production.
If you need to produce shallow-drawn standard food containers, run-of-the-mill takeaway boxes, and barbecue trays for normal application, H24 is the right choice for you.
As these items can be produced without the need for deep cavity stretching, H24 has higher yield strength and allows manufacturing rigid trays.
The finished trays will not change shape while being filled with hot food items, will not be dented when being pressed vertically, and will exhibit perfect performance during multi-layer stacking in warehousing and logistics.
H24 is not an effective option everywhere.
For deep-drawn aviation meal boxes, deep-dish containers or multi-creases moulds applications, temper H22 will help achieve the high level of ductility and avoid tears and wrinkles in high-speed stamping process.
Managers in different manufacturing plants are faced with the dilemma of choosing between H22 and H24 due to the conflict between yield rate in stamping and rigidity of finished product.
The simple solution to avoid losses is to come to the HQ of HTMM for advice regarding the right temper.
The only time-consuming thing is to provide the manufacturer with your production conditions, like the speed of stamped machinery, depth of mould, size of trays and required rigidity of boxes.
The HTMM professional will help you decide if it is H22, H24 or something between that will work for you.
HTMM provides container-grade jumbo rolls, as well as complete packaging solutions that encompass both household foil and flexible packaging.
Thus, when purchasing foil tray raw materials, you are able to obtain all types of aluminum foil from one source.
The company supplies 8011 alloy jumbo rolls that can be rewound into retail household foil for the kitchen market.
HTMM has also mastered the production of aluminum foil for flexible food packaging (8079 and 1235 grades) with the guarantee of perfect barrier properties.
There is no need to look for separate suppliers when ordering producs like container foil, household foil for retail purposes, and multilayer flexible packaging materials, so procurement management becomes much easier.
The reason why global buyers consider HTMM to be their long-term partner is not that it is a reliable manufacturer of aluminum foils but also for other advantages in its operations that make it superior to the trading companies.
First and foremost, HTMM uses the factory-direct sales approach, which helps it to avoid any kinds of mark-ups caused by the presence of the intermediate companies.
The company is one of the leading aluminum foil manufacturers in the United States and has its huge primary production facility that produces jumbo rolls of aluminum foil that can be sent straight to international customers without any intermediary companies between them and HTMM.
In light of the above, there are no resellers who can impose any mark-ups onto the prices charged by the company, thus allowing the final recipients of HTMM’s products to receive highly competitive factory prices.
In turn, this contributes to stabilizing the costs of raw materials for the packaging industry and maintaining profitability amidst changing world prices for aluminum.
Secondly, consistent quality and adhering to international food–contact regulations ensure that exports pose no concerns.
HTMM’s aluminum foil complies with all international standards of food safety set by the relevant control organizations as per the established rules.
The composition of the raw materials, cleanliness of the surface, and migration of harmful substances undergo thorough examinations in the laboratory.
Thirdly, robust sea packaging protects jumbo rolls during long-distance shipping.
Jumbo foil rolls are heavy and susceptible to scratches or oxidation caused by water and air.
Hence, HTMM employs wooden fumigation-free crates as well as suspended and sealed packaging.
Rolls are secured in wooden crates and do not touch the wooden surface, while sealed packaging prevents moisture vapor from getting inside the crates.
After sea shipment, jumbo rolls are delivered undamaged, without any dents or scratches.
In this way, you can get your goods in good shape as soon as they reach the destination and avoid losses incurred by damaged products.
Fourthly, high production capacity and steady lead times keep your production running effectively.
Thanks to the entire industry supply chain in China, HTMM can deliver high-quality products in required quantities – 3003, 8011, 8079 and 1235 foil products.
Once the delivery deadline is known, HTMM delivers supplies within the specified time.
You will not experience a situation of your production waiting for materials to arrive.
Long-term partners are welcome to reserve an amount of their products with HTMM which will result in getting supplies on time.
In conclusion, for shallow-drawn takeaway containers and BBQ trays that require superior rigidity and stackability, temper H24 is ideal, while temper H22 is more suited for deep-drawn complex-shaped foil containers.
If you still have doubts, you can always reach out to HTMM's technical team for affordable temper recommendations.
With a wide range of alloys at factory prices with world-class food-grade quality, HTMM is your reliable permanent supplier of aluminum foil products.
